I thought I'd start this thread to let people know that besides the heat issue, my MBP is pretty impressive as far as speed. It's a 15 inch with 1.8 processor and 1.5 gigs of ram. The other day I was running Final cut express, title motion pro, soundtrack, loops, coreduotemp, virex and had a few firefox windows open. I was using expose to switch back and forth quickly, and I didn't have so much as a hiccup. After a minute it started to all sink in, and I was just thinking that my windows machine probably would have crashed before I even got all of those programs open. Occasionally a program takes a tad longer to open than I would like on my MBP, but it wasn't until I had all of this stuff running at once that I truly began to appreciate the power of the coreduo. Anyone else had this happy experience with their duos?
