I recently sold my 2010 13" Macbook Pro and have been considering buying a new laptop. I also have a 3rd gen iPad, so I have some reservations about going with the 11" Air since the iPad can serve as my go to device for when I want something really mobile for reading and web browsing. The reason I am leaning towards an Air over a Macbook Pro is because I really wanted something light but also capable of doing something more than just consuming (the Microsoft surface actually looks like a pretty good hybrid of what I want). The 13" i5 with 8GB of RAM is what I think would be ideal, but I can't decide if I should go with 128 SSD or the 256. I would prefer to be able to run Windows 7 in bootcamp as I need to run Windows for most of my work. The only reason I really need to run OSX is for a medical imaging program called OsiriX that only runs on OSX. Honestly, aside from this one program and the fact that I love Apple's hardware, I would probably be inclined to pick up one of the new Zen Primes. But I loved the quality of my Macbook Pro and do like some of the features of OSX and the versatility of having the ability to use both operating systems. With all that being said I really am trying to decide the following based on my needs: Should I go with one of the 2012 Airs or go with a refurb from last year? If I go with a 2012 model should I go with 128 or 256 for the SSD? I have a desktop running Windows 7 that has a ton of storage so I don't necessarily need to store a ton on the Air, but I worry that running Windows 7 in Bootcamp and having duplicate files on each partition may eat up a bit of room. Should I even consider a 11" given that I have an iPad? Thanks for the input.
