Should you get an AIO with a traditional or ultra-wide monitor? The majority of AIO computers feature traditional widescreen monitors with the same 16x9 aspect ratio as a TV. That said, “ultra-wide” screens – single, elongated screens that deliver the desktop space of two 16x9 monitors side-by-side in one monitor – are becoming increasingly popular.

• Ultra-wide screens are ideal for workers who need to see more of a spreadsheet all at once. They’re also helpful for people who prefer to view documents or browser tabs side-by-side.

• Traditional 16x9 screens are significantly more affordable, so it’s worth it to spend some time considering which form factor is best for you.

Should you get a curved-screen AIO or a flat-screen AIO? The debate between which screen type is better will never die, because both are largely a matter of personal preference.

• Curved screens mimic the curvature of the human eye, in theory delivering a more immersive visual experience by involving peripheral vision – as long as only one person is watching the screen, that is. Because screen curvature is built around a single user seated in the middle, anyone sitting on either side of the screen won’t be able to see everything, which can make collaboration tough.

• Flat computer screens, in contrast, don’t involve peripheral vision and are easily seen from any angle.  

Picking the right size screen for your all-in-one computer is a big decision – one that you can’t go back on or leave for a later upgrade! All-in-one computer screen sizes range from 21” to 34”, although 24” is the most common. As you’re deciding what size to go with, think about your own space and your most typical computer tasks. Do you have enough room on your desk for a 34” screen? Will 24” be enough for your everyday applications?

No computer-buying experience is complete without asking the age-old question, “Would you like a Mac or a PC?” Nowadays, the choice has more to do with your personal preference than it does with functionality. Macs and PCs can perform the same tasks, albeit in very different ways, so in this context, it makes more sense to consider your own circumstances and taste.

Give some thought to whether the apps you use most are available exclusively on either Windows or Mac. Also, consider whether your other devices, such as smart watches and gaming consoles, integrate better with one operating system or the other.

If you’re interested in upgrading your all-in-one’s accessories, here are your best options.

Wireless keyboard - Microsoft Surface Ergonomic Keyboard

Microsoft continues to churn out high quality accessories from their Surface brand, and the Surface Ergonomic Keyboard marries that iconic style with a layout that’s a lot better for your wrists than a standard keyboard. Despite being a Microsoft product, the Surface Ergonomic Keyboard is Bluetooth, so it works across platforms — it’s even great on a Mac. Minimalist looks, feather-light keys, and an ergonomic approach make this an easy choice. 

Wireless mouse - Logitech M705 Marathon Wireless Mouse

There are all kinds of options available when it comes to picking the right computer mouse, ranging from minimalist single-button designs to models with multiple programmable buttons and LED lighting. Logitech’s M705 Marathon is the perfect middle ground: it can be a reliable straightforward mouse, and it’s also got programmable buttons for those who need a more specific configuration. Plus, it has a USB Unifying Receiver so you can use a Logitech wireless keyboard with the same wireless connection (and not have to give up another USB port). Whether you need something simple or flexible and reliable, this is one of your best options.

Computer speakers - Edifier R1280T Powered Bookshelf Speakers

Edifier makes some of the best computer speakers in the world, and their entry-level R1280T speakers live up to their reputation. They’ve got multiple inputs so you can connect your computer’s audio as well as a secondary audio device like an Amazon Echo. But the big deal here is the sound: with rich bass, smooth mids, and crisp highs, they’re sure to satisfy any audiophile and make your computer’s music sound amazing.

It’s easy to get sticker shock when shopping for all-in-one computers, especially when the prices can be double or triple the cost of a traditional desktop computer. But size comes at a premium. All-in-one computers are essentially laptop components built into a monitor, so pricing is better aligned with high-end laptops. When you consider everything that’s included (a monitor, keyboard, mouse, and speakers), many all-in-one computers are an unexpected bargain.

Most all-in-one computers were not made to be upgraded or modified at all, so it’s important to pick one that’s adequate for both the present and the future. When it comes to future-proofing your machine, there are three main components worth investing in.

• CPU: Your computer’s Central Processing Unit (CPU) is the heart of it all, so be sure you have one that’s up to the task. When checking out specific models, look at what generation of CPU is inside (e.g., 7th-generation Intel i7), and determine if that generation is reasonably current. (Avoid CPU iterations that are more than two years old.)

• RAM: Your computer’s Random Access Memory (RAM) strongly influences its ability to run multiple tasks simultaneously. Most all-in-one computers have models available with more RAM than the base model, and those are a worthy upgrade.

• Hard drive: Consider both the space and type of hard drive you’re looking for. If you need a lot of space, you may want to opt for a platter-based hard drive. If you prefer speed and don’t need as much room, consider a solid-state hard drive (SSD).

When you’re comparing all-in-one computers, keep the following tips in mind.

• You may not need a “cutting-edge” model. Your choice of computer should depend more upon how you’ll be using it than whether it has the latest, greatest technical specifications. If you plan to use the computer for processor- and RAM-intensive tasks like video editing, gaming, or graphic design, get the best computer you can afford. If you plan to use it mainly for web browsing, email, documents, and the occasional movie, a more basic model would likely suffice.

• Make a plan for any mobile computer needs. All-in-one computers do a lot of things well, but traveling is not one of them. If you need access to your files when you’re away from your computer, consider signing up for a cloud hosting service. If you frequently need a change of scenery while you work, consider a laptop instead – because you can’t take an all-in-one computer to your local coffee shop.  

• Determine how many USB ports you’ll need. Tabulate the number of accessories and gadgets you’ll need to connect to your computer via USB; your printer, phone, smart watch, and even your portable flash drives will all need ports of their own. If your all-in-one computer doesn’t have enough available USB ports, consider buying a separate USB hub.

Q. Can I add a second monitor to an all-in-one computer?
A. Most, but not all, AIO computers have ports for connecting a second monitor. If you absolutely must have a two-monitor setup, make sure the all-in-one computer you buy has an HDMI or DisplayPort video port.

Q. Will I need to buy separate speakers?
A. Most all-in-one computers come with built-in speakers which are adequate for video conferencing and the occasional YouTube video. If you’re going to be doing any critical listening on a regular basis, you’ll want to opt for a separate set of speakers or headphones.

Q. Can I use an all-in-one computer for gaming?
A. Yes, but don’t expect miracles. Computers rely heavily on their video cards to render intense graphics with high motion, and most all-in-one computers come with video cards better-suited for casual use. Gaming is still a possibility on an all-in-one computer, but keep your expectations realistic; think more along the lines of Candy Crush than Call of Duty.
