Last week, I installed Ubuntu 10.10. This wasn't the first time I tried Ubuntu but the first time I gave it a real and fair try.
The first time I tried it was in 2008, when I got a new Laptop. Three hours later I uninstalled it because I coudln't get to work the wifi card of my laptop.
Now with 10.10 everything works just fine and after a couple of days of trying it out, I'll decided to switch from W7 to Ubuntu for good.
I set up dual boot, because I want to play some games and need some programs that only exist for windows, but for five days now, I haven't booted into Windows.
After setting everything up, trying everything what's there, clickin on every menu and my first time in the terminal (only experience with this is DOS prompt), I realized it's really awesome and that I gave up way too early the other times I tried it.
What OS are you using?
