What would you choose? Currently I have the former, but am considering just buying a decent display if I ever switch to a MBA to use as an extension as to combat any screen size related hinderance in productivity (excel and accounting software is what I mainly use for my job). I feel the MBP 17 encourages me to use my ipad a little more when it comes to consuming (browsing, reading, games), which is great, but I'm wondering if I'll start to use it less if I have an air. Sorry I wasn't sure if I should put this in another section. Any input would be appreciated.
