I'm glad i can find most of the useful applications in Ubuntu once i installed it (not like in windows... takes 1 hour to install 1 day to get all software up and running). But...
Ubuntu would need a tutorial that could be found on the desktop in LiveCD mode, or after the installation, for new users, and also, Wine should be pre-installed in case somebody hasn't an internet connection.
This is my personal opinion. What do you guys think ?
