Hey everyone, I'm in the market for a new laptop and have been a long time PC user that's still on the fence of whether to convert to a Mac or not. I've been debating whethert to get the MPB 13'' or a Sony Vaio EB or F series. I've just had bad experiences with PC laptops in the past (slowing down, windows crashing, applications basically not working right) with different machines like Dell, Gateway and HP. My dilemma is that I can go with a Sony Vaio -- which i've read mostly positive reviews about, and get a machine with a faster processor and some additional accessorial features. If I go with the Macbook 13'', it's the older Duo Core processor and I'm paying a bit more. The question is for for PC users who switched over to Mac, do you find that much of a difference? Is it worth it? I'm not sure I want to spend the money to get the 15'' MBP with the higher processor, but if the machine lasts quite awhile then I do not mind. Every PC I have had has slowed down within 1-2 years of my purchase. Any help would be appreciated. Thanks.
