I am formatting an older computer and it'll be simply be used to browse the internet, instant messaging, and creating/reading documents and the occasional PokeStars game (which, according to <a href="http://www.thepokerbank.com/rooms/pokerstars/ubuntu/" target="_blank">this</a>, I can do). I'm not going to purchase another version of Windows 7 just to do these things. However, I've heard that each update of Ubuntu runs slower and slower. If that is the case, I'm not sure I can even run Ubuntu on this thing with its 1GB of RAM... I really know nothing about Linux so I'm not sure if I should go ahead with this... what do you guys think?
