I've recently installed Hardy on my desktop. I was getting fed up of WXP being v e r y s l o w and crashing lots. My Bro is a long-term linux user and pointed me in the direction of Ubuntu.
At first, it was installed and little used, old habits and all that. I decided to make the leap and go for Ubuntu as my default use. I only went back to XP for specific software.
I've not used XP for days now (except at the moment cos I'm on a laptop which refuses to install Linux (GRRR!)). I'm really getting the hang of things with Ubuntu.
As a 'basic' user its dead easy, everything makes sense. It took me a while to get the PC to talk to my network storage device. Once that solved it was a matter of changing the shutdown order so it unmounted properly.
I'm enjoying learning, i'm enjoying using.
Overall, I'm positive about being a full convert!
