I want to get a pocket CD to keep in my wallet with a live OS so I can get "my own personal computer" on any pc I use, and I just wanted to know if I would be able to go with pocket DVDs or pocket CDs. I want it to be able to be as compatible as possible, so I just wanted to know how many computers are still out there that have cd drive that cannot read dvds?

You would not be able to maintain files between OS sessions if you run from a CD. You should look at putting an OS on a USB flash drive since USB is pretty universal. Heck, USB stands for Universal Serial Bus. And further in line with your question, no one can really answer that for you. I would think that in places that use really old computers, you would be out of luck in using a CD. For example, maybe libraries or schools or some charities. But then again, the cost of maintaining and trying to get old equipment far outweighs the cost of buying new equipment (doesn't have to be high-end). Hence, I would think you'd be hard pressed to find a computer out there that does have the ability to read DVD's.

+1: USB sticks are more compact, and (unless it is a very cheap USB stick) faster. –  Richard Mar 2 '11 at 9:05
    
I thought about USB, but are there a lot of computers that can boot from USB? That is why I was thinking CD. –  Sean Mar 3 '11 at 4:10

What you require is rather using Portable applications, defined as :

a computer software program that is able to run independently without the need to install files to the system it is run upon

The best site for these is PortableApps.com. See also their Portable App Directory.
You can also use their PortableApps.com Suite :

PortableApps.com Suite™ is a complete collection of portable apps including a web browser, email client, office suite, calendar/scheduler, instant messaging client, antivirus, audio player, sudoku game, password manager, PDF reader, minesweeper clone, backup utility and integrated menu, all preconfigured to work portably. Just drop it on your portable device and you're ready to go.

However, this suite is just a starting point. Today, many products have a portable version in addition to the installed version. You can therefore create yourself on a USB disk/key a collection of useful tools, as do many computer professionals.
