I've been quite busy today Kitty, no time for a walk - plus the weather has been carp.
I've upgraded from Gutsy Gibbon to Hardy Heron on my laptop, but I've got no further yet. Seems fine so far and I'll do the further upgrade to Intrepid Ibex when I've time.
I burned the Intrepid live CD yesterday and today I installed it on my friend's Vista laptop as a dual boot set-up. It all seems to be working fine so far - fingers crossed!
You're right about how useful the live CD is - I was able to try out potential problem areas like wireless networking using the CD before doing the actual installation.
I had to reduce the size of the Vista partition to make room for Ubuntu. Fortunately Vista provides a basic partitioner which seemed to do the job OK - GParted which I normally use states that it can't always handle a Vista partition correctly and you might end up being unable to boot into it.
I had my laptop in the kitchen and the other one in the living room, so had to keep dashing from one to the other to see if various things had finished. Might have been easier if I'd had them both in the same room
