What doesn't kill you makes you stronger I suppose. And if I have to do another software update I'm going to be the strongest man alive. I recently upgraded to OSX 10.6. I had a single reason for doing so: a bug in apple's openGL implementation meant my favorite program, blender, didn't work. It would crash after just a few minutes of use- every time.
10.6 fixed that error, and I must say Blender's been working excellently for me. I just can't believe it took an entire system software upgrade to fix that one little but.
I'm happy about that, but a little upset that exposé now shows me windows scaled to funny proportions. I liked this better before. A lot of people are complaining about the blue glow, that doesn't bother me in the slightest, but the weird scaling for windows in exposé greatly reduces its usefulness, for me at least. David Trang seems to have summed up most of my thoughts on the matter, so if you want to know what I honestly think of the new exposé size, see his thoughts.
The upgrade did inspire me to go hunting again for a solution to one of the worst things about the new macbooks. Namely, the absence of a numpad on the uio-jkl keys. For a lot of people it didn't matter, but for those of us who used it, that was a major cripple.
