Just upgraded my dual 2.5 to OS X Tiger 10.4.3 and I'm disappointed in the speed drop in almost everything. I get the spinning beach ball more than ever. My computer's remaining Hard Drive space initially dropped about 80 GB when I first booted under Tiger, then dropped another 40 GB the second time I booted, but now is back up 70 GB to the good. Crazy! Is this typical for an upgrade to Tiger??? I kinda wish I had stayed with Panther. Jerry
