The next time you're online and thinking that you need a bigger screen than your current laptop or tablet has, look at an all-in-one desktop. You may be surprised how much screen and power AIO PCs deliver for the money versus a like-priced laptop. If you're not sold on an AIO, though, be sure to check out our top desktop picks overall, as well as our favorite desktops for work and PC gaming.

On the most basic level, one of the main reasons for choosing an AIO is that you don't need to buy separate parts, like a monitor and speakers. All-in-one PCs represent exactly what the name implies: a complete desktop computer in one package, delivering a plug-and-play experience. Your screen and components are all tied up in one device, like a laptop, which takes up less of your desk or floor space than a desktop tower and monitor combination.

Even if you find a laptop you like with a roomy 17- or 18-inch screen, you'll need a strong back to carry it anywhere; 6 pounds and up, plus an AC adapter, is typical for machines like these. We suspect you won't travel with a desktop-replacement machine like that all that much, which could make even a small-screen AIO a viable stay-at-home alternative. And because AIO desktops are plugged in, you won't ever run out of battery power.

Because AIOs tend to use more powerful processors than many thin laptops do, a well-chosen all-in-one PC could execute CPU-intensive tasks more rapidly, on the whole. Some 3D games will run better, too, thanks to the discrete graphics chips in some A-grade AIO PCs. To find AIOs with discrete chips, look for one of the few AIOs with graphics solutions dubbed GeForce RTX, as opposed to Intel Iris Xe, UHD, or HD Graphics, or AMD Radeon (no "RX") integrated graphics.

Other advantages? You can share the PC among family members and use it to store centrally accessible photos, music, and videos. And a large, widescreen AIO PC makes for a fine videoconferencing system. Rather than having the family crowd around your iPad or a little laptop screen during calls, seat them in front of a 27- or 34-inch AIO desktop so you're not subconsciously squeezing together to "fit on the screen." Plus, a large AIO screen is ideal for watching a movie from 5 or 6 feet away, so a couple in a studio apartment could use a big-screen AIO as a TV in front of a small sofa or loveseat. Or, if you place the system in a central location, such as your kitchen counter, you can monitor your children when they're online.

But these PCs aren't just suitable for play. A few years back, Apple brought the AIO further into workstation territory with the iMac Pro. The starting price for this monster machine at launch was high, at $5,000, but it packed a jaw-dropping amount of muscle: It had a 27-inch 5K screen and was configurable with up to an 18-core processor, 128GB of memory, and 4TB of solid-state storage. (Note that you may still find it for sale from non-Apple sources, usually used or as a refurbished model, but as of March 2021, Apple discontinued it.)

This kind of muscle is usually found only in elite-grade tower PCs. We haven't seen a brute-force AIO to rival the iMac Pro since, but today's top-equipped AIOs can rival at least a decently equipped tower desktop. Apple's homebrewed M-series chips in the latest iMacs mentioned are fast. And while many Windows AIOs trend toward the budget side, you'll find some models with quick processing options.
