All about all-in-one computers

The computer market these days is flooded with different makes and models of personal computer which can make the task of choosing the right PC for you a very frustrating one.  There are laptops, netbooks, ultrabooks  tablet, phablet, desktops and now the insurgence of the all-in-one to choose from.

What is an All-in-one PC?

It is a compact personal computer with an integrated monitor which is designed to consume less power and take up less space than a regular, typical desktop computer.  It houses all its components (apart from the mouse and keyboard) in a single case and tends to run very quiet.  It can also double up as an excellent media center system in your living room (or bedroom).
It's also important to note that several of the all-in-ones available on the market today also sport touchscreen capability.

Are they any good?

Yes!  But as with anything tech the pros and cons must be carefully weighed before spending your hard earned cash

PROS:

1. The are compact and require little space for set up
2. The consume less power then regular desktop computers
3. The are extremely easy to setup
4. They are crazy stylish
5. Easier to relocate in your home or office than the regular desktop
6. Can double up as a media center
7. Some can be used as a television (must have video/graphics input connectivity)

CONS:

1. There is little room for expansion (you cannot just add another hard drive or optical drive)
2. If one component goes, the entire unit must be taken to the repair shop
3. Most all-in-one are built using laptop components which means they will not be able to perform as well as equally priced regular desktops
4. Repairs/replacement of bad/failed components will be somewhat more costly than for that of a regular desktop.

What to look for?

1. Get a big enough screen (at least 21 inches) with the best quality resloution you can afford (1920 x 1080). Remember you CANNOT replace/change the display later.
2. Check the ports. Ensure the PC comes with the connections you will be needing (a video input port should be considered which would allow you to use the screen as you would a television)
3. Get a processor with future potential (at least an Intel core i3 or AMD Phenom III)
4. At least 4GB of RAM.
5. A 7200rpm hard drive (you can decide on its size based on your needs)
6. Discrete graphics if you'll be gaming else integrated graphics would be just fine
7. WiFi capability should be considered
8. Wireless keyboard and mouse would be nice as well.

NB:  There is NO BEST, it's all about which one BEST satisfies YOUR needs.
