I'll be keeping my XP running for some time... I had already decided that Vista is not a necessary upgrade for me.
I actually came to the same conclusion as well, some time ago just as you.
Other than being 'pretty', vista doesnt really show me much.. XP still recognizes most of the devices I plug into it, and it still does what I need it to (and then some).
Once you get all the tweaks out of the way, its a decent o/s.
Although, I must point out that XP home only allows a max of 10 network connections to it, so these restrictions are really no supprise move from M$
