I read about the iLap on these forums when i bought my laptop 7 months ago but never wanted to spend the 50 bucks in it. Well I bought it a week ago and now I am kicking myself for not doing it sooner. I have had my pb on for 6 hours now charging, running movies, burn dvd's and everything and the fan has yet to kick into high gear once! the palmrest beside the trackpad is still warm but not hot like it normally gets. It is sweeet. Just thought I would share.
