I love provocative titles like that!
I finally caved and scrapped vista on my 4 year old Dell D610, its a pentium M 1.6 and did have a recent 2GB ram/120GB 7200RPM hard disk upgrade but lets be frank, its not really vista worthy (and I really wasn't willing to turn off all the vista features I like just to stick with it) so to coincide with the launch of Hardy Heron I wiped it and put Ubuntu on there, running a lot cooler now for starts!
The laptop has a pretty light workload in all fairness, web browser and movie playing mainly, but some memory leak in firefox caused the thing to eat up over 300mb of memory whenever there was a flash ad somewhere on a page, and hog CPU cycles, and as the thing barely managed to run vista to begin with you can understand the issue
So far the only issue I have had is installing 7z has only given me the CLI version and not a GUI version via the ubuntu package manager, might have to just apt-get the guified one or find the .deb file on the website
Skype is running fine, Firefox 3 beta comes standard and I installed VLC pretty quickly (although it doesn't like playing direct from SMB sources, although if you start VLC and ADD the SMB source it works fine!)
Aside from that, all the hotkeys seem to work (brightness, volume etc) which is ace for linux (atleast compared to my previous experiments on laptops) and the wireless works (although I cant get it conneted, probably me forgetting hte password ;)
I've always been a horses for courses kind of guy, and finally decided my old laptop just wasnt cut out for Vista, it's nice to have a linux system running in the house again (phased out my Gentoo file server 2 years ago, and my Openfiler system a year+ ago)
