So after wondering whether to wait or not for merom, i decided to head to the apple store and buy the 2.16 15" mbp and I'm loving it. No whine at all so far, and while it does get a bit hot, I've already ordered a laptop stand with fan for it. The adjustment to the new OS took a couple of hours, but I feel like I'm getting the hang of it. A couple of questions though: When I see screenshots of certain people's desktops, they get their HD icons on the desktop to display how much space is taken up and not taken up...how do they do that? All mine is just a boring Macintosh HD. Also, for expose, F11 and F12 work for me. But F9 and F10 do something else. When I press them, this little box with a line and lines shooting out from it appear. Aren't they supposed to relate to Expose? For memory, windows had used memory taken up, and free memory available. Can someone explain to me the mac's idle memory and active memory and stuff? Thanks so much for the help!
