Back then successful installation means a lot. Those were the RedHat 4 days. Heck even ordering Linux CD is not easy. Anyone still remember Cheapbytes?
Just upgraded to Ubuntu 7.10 Gutsy. Damn, I don think I will spend a dime on Vista or Windows unless I am forced to.
To everyone who still hesitates, do it now. It's going to be the smoothest Ubuntu upgrade you will ever have to deal with. There won't be a lingering doubt about clean re-install. I promise.
