Since this thread originally asked for advice about good sidebar gadgets, it has served no useful purpose other than the inevitable boring round of slagging off Vista and Bill Gates.
I don't mind Vista. It boots up very quickly for me, (well under 10 mins - JTbo, you need your pc seriously seen to) I don't have a ram problem and I like the gadgets in the sidebar, my pc does not suffer performance problems from having 5 running at once.
The ones I use are the CPU dials, weather, clock, post-it pad and the LFS S3 countdown timer.
