The Best All-in-One Computers: 4 Compared (and One to Skip)
We compared four current all-in-one desktops for home and family use on screen quality, everyday speed, value, and how little clutter they leave on your desk.
The short version
For a home or family desk, the Apple iMac 24-inch (M4) is the all-in-one to beat: a stunning screen, silent speed, and the least fuss of anything here. Windows families who want a big, premium canvas should look at the HP OmniStudio X 31.5-inch, which pairs a huge 4K display with modern internals. The Lenovo IdeaCentre AIO 27 is a smart-value pick if you can accept a lower-resolution 27-inch panel. The Dell 24 All-in-One is the one to pass on, asking mainstream prices for entry-level memory and a plain screen. Best for: most families the iMac, big-screen Windows households the HP OmniStudio X, and budget-first buyers the Lenovo.
The verdict in 30 seconds
What mattered most
- Screen size
- Screen sharpness
- Operating system
- Everyday speed
- Touchscreen
- Desk footprint & tidiness
An all-in-one desktop hides the whole computer behind the screen, so the whole family gets a real workstation without a tower, a tangle of cables, or a separate monitor. The field in 2026 splits cleanly: Apple's iMac still sets the bar for a calm, polished experience, a couple of big-screen Windows machines make a genuine case, and at least one mainstream option is quietly outclassed. Two of these four are easy recommendations, one is a maybe, and one is the machine we'd steer families away from.
The most polished, lowest-hassle all-in-one you can put on a family desk.
Best for: Families who want a beautiful, reliable, near-silent computer and are comfortable in macOS.
- Gorgeous 4.5K Retina screen that looks sharp and color-accurate straight out of the box
- M4 chip stays fast and completely silent under normal family workloads
- Genuinely tidy: one thin panel, a colour-matched keyboard and mouse, and a single power cable
- Only a 24-inch screen, with no larger option in the line
- Memory and storage are fixed at purchase and can't be upgraded later
A huge, sharp 4K Windows canvas for families who want the biggest screen in the house.
Best for: Windows households that want a big, premium shared screen for schoolwork, media and multitasking.
- Enormous 31.5-inch 4K display with room for several windows side by side
- Modern Intel Core Ultra internals handle photos, video calls and light creative work with ease
- Height-adjustable stand and a strong port selection make it easy to live with
- Commands a flagship price, and the sheer size dominates a desk
- Runs warmer and less silently than the iMac when pushed
A well-priced 27-inch touch all-in-one that's held back mainly by a plain-resolution screen.
Best for: Value-minded families who want a big touchscreen Windows AIO and can live with a lower-resolution panel.
- Large 27-inch touchscreen with a generous amount of memory and storage for the money
- Current AMD Ryzen AI silicon keeps everyday tasks and browsing snappy
- Keyboard, mouse and a pop-up privacy webcam are included in the box
- The 27-inch panel is only Full HD, so it looks noticeably softer than the iMac or the OmniStudio X
- Styling and build feel functional rather than premium
A tidy-looking machine that asks mainstream money for entry-level specs.
Best for: Almost no one at its usual price; only worth a look if it's deeply discounted and paired with more memory.
- Clean, unobtrusive design with a pop-up webcam and a small desk footprint
- Keyboard and mouse are included, so it's ready to go out of the box
- Frequently sold with just 8GB of memory, which feels tight for Windows 11 family multitasking
- A plain 23.8-inch Full HD, non-touch panel for a price that buys sharper, bigger rivals
- Forgettable overall: nothing here beats what the other three do for the money

How we judged the field
We don’t run our own lab. Instead, we synthesise independent testing and long-run owner reports, then weigh what actually matters for a computer that lives on a family desk rather than in a spec sheet. Four things carried the most weight.
First, the screen: an all-in-one is its display, so sharpness, brightness and colour matter more here than on almost any other kind of computer. Second, everyday speed and noise: family machines spend their lives juggling browser tabs, video calls, homework and streaming, and the best ones do it quickly and quietly. Third, how tidy and livable the whole package is, from cable clutter to whether a keyboard and mouse are included. Finally, honest value: not the lowest price, but how much useful computer you get for the money, keeping in mind that most all-in-ones can’t be upgraded later. Reviewers and owners broadly agree on where each of these machines lands, and that consensus shapes the verdicts below.
Apple iMac 24-inch (M4) — buy
The iMac remains the one to beat. Independent testing consistently praises its 4.5K Retina screen as one of the sharpest, most color-accurate panels in any all-in-one, and owners note how good it looks with zero calibration. The M4 chip keeps the machine fast and, crucially, silent — there’s no fan roar during a video call or a pile of browser tabs. It’s also the tidiest computer here: a single slim panel, a colour-matched keyboard and mouse, and essentially one cable to the wall.
The trade-offs are real but narrow. You’re limited to a 24-inch screen with no larger option, and the memory and storage you choose at checkout are the memory and storage you keep for life. For most families, neither is a dealbreaker — but it does mean buying a sensible configuration up front rather than the cheapest one.
HP OmniStudio X 31.5-inch All-in-One — buy
If you want to stay in Windows, or you simply want the biggest, most impressive screen in the house, the OmniStudio X is the standout. Its 31.5-inch 4K display is enormous and sharp, with genuine room to put documents, a video call and a browser side by side. Modern Intel Core Ultra internals handle everyday tasks, photo work and light creative jobs comfortably, and reviewers highlight the height-adjustable stand and generous ports as things that make it pleasant to actually live with.
It asks a flagship price, and that giant panel takes over a desk. It also runs a little warmer and less hushed than the iMac when you push it. But as a premium Windows all-in-one for a family that wants scale, it delivers.
Lenovo IdeaCentre AIO 27 — it depends
The IdeaCentre is the value play. You get a large 27-inch touchscreen, a healthy amount of memory and storage for the money, current AMD Ryzen AI silicon that keeps browsing and everyday apps snappy, and a keyboard, mouse and pop-up privacy camera in the box. For a lot of families, that’s plenty of computer at a friendly price.
The catch is the screen: on a panel this large, the Full HD resolution looks noticeably softer than the iMac or the OmniStudio X, and that’s the first thing sharp-eyed owners tend to mention. Styling is practical rather than premium. Whether it’s the right buy comes down to price and priorities — if a big touchscreen and low cost matter more than pixel sharpness, it’s easy to recommend; if the screen has to look crisp, spend up.
Dell 24 All-in-One (EC24250) — skip
On the surface the Dell looks fine: a clean design, a pop-up webcam, a small footprint, and a keyboard and mouse included. The problem is what you get for the money. It’s frequently sold with just 8GB of memory, which feels tight for Windows 11 once a family piles on browser tabs and video calls, and the 23.8-inch panel is a plain, non-touch Full HD screen at a price that buys sharper and bigger rivals.
Nothing about it is broken — it’s simply outclassed. For the same outlay you can get the Lenovo’s larger touchscreen, and for a bit more the iMac or OmniStudio X are in a different league. Unless you find it deeply discounted and can pair it with more memory, this is the one to walk past.
Apple iMac 24-inch (M4) vs HP OmniStudio X 31.5-inch: which should you buy?
These are the two we’d hand to a family without hesitation, and the choice mostly comes down to ecosystem and size. The iMac wins on refinement: a flawless screen, silent operation, effortless setup, and the tidiest desk of anything here. It’s the low-stress choice, especially if you already use iPhones or iPads.
The OmniStudio X wins on scale and familiarity. Its 31.5-inch 4K display is far bigger than the iMac’s 24 inches, which is a real advantage for multitasking, shared viewing and anyone who finds macOS unfamiliar. It costs more and takes more room, but for a Windows household that wants a premium centrepiece, it’s worth it. Put simply: pick the iMac for calm, compact polish; pick the OmniStudio X for a big Windows canvas.
What to look for
- Screen first. On an all-in-one the display is the product — favour a sharp, bright panel, and be wary of Full HD stretched across a 27-inch-or-larger screen.
- At least 16GB of memory. 8GB is where family multitasking starts to drag; 16GB is the comfortable baseline in 2026.
- Fast, roomy storage. Aim for a 512GB or 1TB solid-state drive, and avoid tiny or slow storage on bargain models.
- Remember it’s hard to upgrade. Most all-in-ones seal everything behind the screen, so buy the specs you’ll need up front.
- Check what’s in the box. A keyboard, mouse and a webcam (ideally with a privacy shutter) save money and hassle.
- Match the operating system to your family. Choose the platform and software your household already knows.
Our final take
The all-in-one category is in good shape, and for most families the decision is refreshingly simple. The Apple iMac 24-inch (M4) is our top pick: it looks superb, runs silently, sets up in minutes and leaves the cleanest desk. Windows households, or anyone who wants the largest premium screen available, should buy the HP OmniStudio X 31.5-inch with confidence. If budget leads, the Lenovo IdeaCentre AIO 27 is a sensible big-screen compromise as long as you accept its plainer panel. The Dell 24 All-in-One is the outlier — not bad, just beaten on value at every turn — and it’s the one we’d skip.
Questions, answered
Is an all-in-one better than a laptop or a mini PC for a family?
It depends on how you use it. An all-in-one gives you a big, comfortable screen and a real keyboard at a fixed spot in the home, which suits shared homework, video calls and media far better than a small laptop. It's less portable than a laptop and less flexible than a mini PC (where you pick your own monitor), but for a permanent family desk the tidy, everything-included nature of an AIO is a genuine advantage.
How much memory and storage should a family all-in-one have?
For comfortable Windows 11 or macOS multitasking in 2026, aim for at least 16GB of memory; 8GB is where things start to feel sluggish once you have a browser, video calls and a couple of apps open. For storage, a 512GB or 1TB solid-state drive is a sensible target, and it's worth avoiding tiny or slow storage on very cheap models. On machines like the iMac, memory and storage can't be upgraded later, so buy what you'll need up front.
Do I need a touchscreen on an all-in-one?
Not usually. A touchscreen is nice for kids, quick scrolling and casual browsing, but on a desktop most people rely on the keyboard and mouse. Among these four, the Lenovo offers touch and the HP does on some configurations; the iMac does not. Treat touch as a bonus rather than a deciding factor.
Should I choose macOS (iMac) or a Windows all-in-one?
Pick the system your family already knows and the software you rely on. macOS on the iMac is smooth, secure and low-maintenance, and pairs naturally with iPhones and iPads. Windows offers the widest app and game compatibility and more choice in screen sizes and prices. Neither is 'better' outright; the right call is whichever fits your existing devices and habits.
Can I upgrade an all-in-one later?
Far less than a traditional tower. Most all-in-ones seal the components behind the screen, so memory and storage are difficult or impossible to change after purchase; the iMac in particular is fixed at the configuration you buy. That makes it important to buy enough memory and storage now, and it's a big reason we favour models that offer sensible specs at a fair price rather than the cheapest sticker.
