My best advice would be to ignore all the glossy endorsements and aggressive marketing from each of these brands that try to convince you that they are the partners of choice. Who cares how much they earn on marketing and in the store than they put into the product!

So, to make your shopping trip a lot easier, here’s my pick of the best all in one desktops for you to buy in 2021.

Frequently Asked Questions (FAQ)

What is the best all in one computer for home use?

As you might have already guessed by the name, these computers are all-in-one desktops. They are highly popular as they combine the functionality of a desktop PC with the portability of a tablet. The design is very appealing and they also consume less power than your typical desktop PC.

What is the best desktop computer for 2021?

The best All-in-one desktop computers in 2021 are the Asus Zen AiO Pro Z240ICG-GR004T, HP Pavilion All-in-One 27-g039wm, and the Apple iMac Retina 5K Desktop.

Given the fact that All-in-one computers are usually more expensive than their regular counterparts, it is only fair to have a solid reason as to why they should be more expensive. That solid reason is the level of convenience and ease of use that comes with buying an All-in-one.

Thus, if you want to have a good laptop without the additional bulk, go for All-in-one computers.

We help you pick the best All-in-One computers for your needs:

Best All-in-one computers for gaming and general use:

Are desktops better than all in ones?

In general, desktops are better than all in ones. They offer more performance for the dollar than their AIO counterparts. They last longer because they don’t have too many moving parts. All in ones, on the other hand, are better for space saving. They don’t take up much space, they can be placed on your desk or a table, and they have the option of being integrated into your home theater systems.

What is the best desktop computer for a family?

We personally would recommend the HP Envy 700-023w desktop computer as the best choice for a family computer. This HP model is a desktop, and it has a zippy AMD quad-core processor and 4 GB of memory. You can upgrade the memory if you are going to be a huge power user on this computer. This is a slick, cool design and the combination of the hard drive and the 2tigabytes of flash memory will zip you around the globe in minutes, no matter what you are doing.

The number one feature in this home desktop computer is the keyboard. It is a one-touch design that allows you to use the keyboard and a laptop screen all at the same time. You’ll be able to surf and write notes using the laptop screen with your left hand while using the computer screen with your right hand.


Over the years, computers have evolved from expensive, complex, space-demanding machines to compact and affordable small devices that can do a lot.

Nowadays, most computer users require them for ‘everyday’ tasks such as surfing the internet, writing documents, messaging, playing games, watching videos, listening to music, etc.

However, you may have a larger purpose in mind or you may desire to upgrade from your existing machine.

If that’s the case, you’d be in the market for an all-in-one desktop computer.
