lol, it's nto that.. if ur gonna have the laptop stationary.. bascially like ur pc, so it never moves.. get the pent 4 HT one. But if you're gonna be mobilve with that thing.. i highly suggest the centrino, they have specific traits that alllows it to save more energy due to battery length. Basically, the centrino chip slows down ur cpu when it's not necessary to have it running at 50 degrees celcius.
if ur gonna keep it at home and plugged to a wall or something, just get the HT
hope that helps
