You looked up and down the internet and couldn't find anything about Linux, Knoppix, or Suse? Hm-m-m-m ...
I have two computers sharing one mouse, monitor, and keyboard via a KVM switch.
Computer #1 has four operating systems on it, installed on two hard drives; these are as follows: Windows98 SE, Fedora 6, Ubuntu (Dapper) and Knoppix 5.1.1.
The second computer has two operating systems installed on one hard disk; these are: WindowsXP Pro, and Ubuntu 7.10 (the Gibbon).
At this moment I am posting the forum from Puppy Linux 2.12, a compressed distro that loads completely into RAM, installs nothing on hard disk, and leaves all disk drives available for other things. Every Linux distro I have mentioned here is a
complete desktop operating system with internet and intranet capabilities, full office suites, cd and dvd reading and burning capabilities, photo editing, graphic design, mathematic, and other abilities. None of these is hard to find or hard to use. The main problem you might have with Linux is finding the one that best suits your hardware. To avoid this problem, start by trying out a live cd. The system will run from the cd and let you try your hardware without installing anything.
There is a great selection of very cheap (like one or two dollar) cds at Edmunds Enterprises on the internet.
