Running Linux on PS3 is the worst experience ever, PS3 is super powerful for a game console, but super lame as a PC. Where to find a PC nowadays with only 256mb of onboard memories, without graphic card support (Sony block linux from accessing RSX)?
A real PC guy who is interested in Linux, and knowing there are computer systems that doesn't come with the floating squares or the partly eatern fruit, should be able to run Linux on any PC, even old one with ease. There is Ubuntu that install very easyly through GUI guidance, and if u're afraid to install into ur harddisk, can always runs Slax on ur thumbdrive.

TV screen, even the HD one are no match for monitor to display test, I always strain my eyes to read the test by using PS3 in-built browser. So why bother? Game machine is meant for games, want to type some word files? Get a PC.
