I deleted the duplicate.If you aren't looking for a high-end GAMING machine, but still would like to be able to stream movies in HD and have notebook capable of multitasking, I'd suggest going for one of toshiba's ultrabooks. I've purchased a Satellite L50 Core i7 and I couldn't be happier.Take it easy, there  are not a lot  of difference between all of them^^
