i'm a pc user and had been planning on switching over with the macbook. i went to the apple store to test it out and it kept stalling and all i was doing was surfing the web with itunes and a word document open (to see how hot it would get etc). the little colored pinwheel thing must have come up like 50 times in the 40 minutes i was tinkering with the computer even for small things like clicking on a link before the page was fully loaded or clicking on photo albums to view pictures etc. it was really annoying. are all macs this stall-happy?
