Hello all, I'm trying to decide if I should keep my 2007 MBP 15 (4GB Ram, 128GB SSD) or get a 2012 MBA 13. I mainly use my current MBP for daily tasks (e-mail, web, facebook, etc.) and remote support (I'm a IT hardware tech who needs to occasionally remote into PC/Macs). I'm leaning towards the Air for battery life and portability but $1199 is a bit of change since I already have a functional Mac that works great (sans battery life. Decisions, Decisions!
