so i have been looking at purchasing a 15" macbook pro with 2.66 ghz i7 and 8 gb of ram and all that good stuff then i see all this stuff on the sandy bridge processor which os supposed to redefine what labtops can do, i looked up the specs or what people have presumed them to be, and it looks pretty insane with a massive integrated graphics card and the whole bit, but i then have to wait 6 months and hope its as good as they say and hope that mac uses it. so is there option to trade it in in 6 months? if yes then for how much? i was hoping to buy one computer and that be the end of it but i would consider this if it was just that amazing!!!
