Hey guys, I've been looking a the MBPs and Airs, and I'm wondering if I will really need a 2011 Mac for my needs, or if Ishould save a couple hundred and get a PC. My needs include : Surfing, watching HD video, Skype / Oovoo, iMovie, and word processing, possibly some gaming as well. Now, my question is, should I spend the 1,100 bucks on a new 2011 base MBP or Air, or grab a refurb , or get a PC? ( I am very interested in OSX and iMovie )
