I hate to fangirl, but...
Zomg, the Ubuntu Dapper Drake LiveCD even detects my usb wireless card flawlessly. All I had to do was enter my WEP key.
The rest of it seemed really polished as well. Granted, I only looked around for ~15 minutes, but it was pretty darn cool. I'm considering taking Ubuntu for a spin on the new laptop I'll be buying sometime this summer--but who knows.
I don't do installations or check out LiveCDs that often, so it's exciting to find stuff that works beautifully when I do.
