I'm currently using a mid-2012 MacBook Pro, but recently I've been tossing up whether I should sell it and get a MacBook Air. My "main" computer is an iMac (desktop) and the MacBook Pro is my "on the go" machine. I travel a lot for work (domestically) and at least x2 a year internationally. I'm tired of lugging my MacBook Pro with me every time I travel, but I'm wondering if the MacBook Air is right for me. I mostly use Word and send emails with my MBP, sometimes I do some photo editing with either Photoshop or Lightroom but I prefer to do that on my bigger machine (thank you, eyesight!). I like the idea that the Air is lighter and far more portable, but I'm wondering if I'm going to hate the 13" screen as opposed to my MBP's 15". I'm also not thrilled that the Air doesn't have an optical drive. If I do switch, I'm looking to do it while my MBP still has some decent value on the secondhand market. I've even considered getting an Air while I still have the Pro, using it for a week and seeing which one suits my work needs better. (A little crazy, I know. I just don't want to be stuck with something I hate and then I can't get my old machine back!) Any MacBook Pro to MacBook Air switchers here? Thoughts?
