since the day it came... no changes as far as Im concerned... was interested in the multi fingered drags on the trackpad, but they dont work here.. I think it show a few extra previews on spacebar... and cover flow view is for everything - hate that anyway.. main thng for me was it freed up 8 jiggers of space... nice... but now i dont care about that either cos i put a 500g HD in the machine,
i would do it, to be updated, but nothing mind blowing happened... OH except .... yes I lost alot of prefs, passwords and settings... which as a pain for the first few days....
