Hi Guys, I come to you looking for a little advice. I currently own a 2013 MacBook Air i7/8/512 and have recently been considering buying an iMac. It has crossed my mind that I might be better off using my MacBook Air with an external display instead of spending $2000+ on an iMac. Most of my time is spent on emails, spreadsheets, and some basic graphic design (nothing too intense). Would I be fine simply using my MBA on an external display, or do you think the case ca be made that buying an iMac is worth the extra money? Thanks for your help guys!
