the_happiness_store: Yeah, Ubuntu seems to abhor the use of a root account. One of its biggest quirks . . . . of course you can always just do a "sudo passwd" and fix it.
Either way, I've had pretty good success with Ubuntu. Especially on alternate platforms it tends to have a far higher probability of working "out of the box" than most other distributions, and includes a well balanced set of applications. I've had great success with it on Mac laptops as an alternative to OS X for slower G3 machines!
