Flash on 64 bit Gutsy didn't work at all for me. Flash on 64 bit Hardy has been working fine
so far.
I totally agree with the lesson in the story. I tried moving my brother to Linux back in 2004
and discovered it was probably 6 years too early. "Terminal?" He was absolutely horrified
and still teases me about it.
At this rate, I think Linux (Ubuntu or Fedora) might be ready to try again in 2010. Even if
flash, mpg and wmv work right out of the box, I'm going to have a really hard time convincing
him to try it again...
