This is odd hearing all the horror stories on here about kernal panics, all peoples email vanishing, spinning beach balls etc etc.
My upgrade to Tiger was totally painless and I did a simple upgrade (by mistake I was too quick on the continue button). Update to 10.1 no obvious problems and hopefully this one seems fine as well.
Mind you I make sure I only install software that I check is Tiger compatible and I always make sure and repair permissions before and after any update. 😉
Not only does it seem faster, but even my G5's XBench score has gone up about 20 points or so. Is it just me, or are images in Safari opening *significantly* faster? 😀
