So i got my First mac August 07, it was the new alum imac. But the low end 20inch 2.0ghz 1GB Ram. Running tiger at the time, never upgraded to Leopard but it I got our New Cat Snow Leopard on it back in August. It actualy slowed down alot after... more reliable, less crashing, but really slowww.... soo i took the plunge and upraded it all the way to 4gb and made a huge difference. But i still feel like its not as fast as it use to be when i first got it. Especial when working with iMovie and editing things, dowloading things... Any helpful hints on what i can do to speed it up. I'll deffinetly get another year and a half out of it. a total of 4 years, but i'm just curiouse if there is any way i can optamize my experience with it.
