I have read a lot of message about hot problem of MBP 13, my last notebook is HP DV2000 which crashed from graphic NVidia heat cycle for once a half year of usage. I decide to buy my first macbook pro. I wanna ask who use MBP13 or MBP15 about cpu or graphic chipset temperature. MBP 15' hot as MBP 13'? if not I will go for MBP15' Thank you for your advance!
