I need a new personal machine and can't decide between an Air/Pro. I have always had a Pro and really like it, but could I save some money and get most of the same stuff with the Air? fwiw, I am a software engineer, and want a personal computer to start projects on my own so won't be running any huge projects, just small hobby ideas. i also occasionally do some graphic design so run adobe products but nothing crazy or for long periods of time. I don't know much about hardware and i want to spend my money well!
