The new MBPs are great they double as a heater for your house. Just turn it on and go to a flash website or type a document in pages and instant heat! Don't leave it on over night though your house will burn down
My MBP runs a chilly 42C while typing a document in Word (maybe Pages is worse, not sure because I don't own it).
Watching the 1080p Dark Knight trailer in youtube it runs low 60's @ 3500 rpm fan speed (essentially silent).
It definitely gets warmer on some flash websites but with judicious fan speed adjustment it really isn't a problem.
But, hey, whatever it takes for you to think your MBP is better.
