Well I can usually get my temp around 105 with simple safari and aim but when i use a snes emulator to play chrono trigger, the heat goes blazing up, thats without any other program on. I usually hit 125 as a max when i just use itunes, aim, safari... someties appleworks. But yeah, i just tried playing the emulator with the big fan blazing and the temp steadily went down to around 147 from 155. I still don't like it because the consistent high heat might do something.
Yeah I tried mimicking the coolpad and podium pad with some boxes and I got the position nearly exact and the temp really didn't vary at all. I was watching temperature monitor the whole time. I found it much comfortable for some reason with the ibook positioned that way but didn't have enough faith in my rickity creation to use it full time. I might buy the pad or something just so i can have it positioned that way
