I've been struggling to decide for several weeks. Here is what I'm considering: Either the MBP (15") or iMac and Refurbished MB. Key things: 1. I wanted a lighter laptop because I have a bad back and carry around a laptop quite a bit; however, the MB is only 0.5lbs lighter than the MBP. 2. I wanted the iMac so I can scan all my documents and save them on the PC. I wouldn't want these docs on the laptop - if I were to lose the laptop, all that data is in the open. This is apparently easily solved by using a network share on the laptop and saving the scanned files to the network. I assume, just like Windows, I can keep the MB from auto connecting to the network share - and be forced to enter a password. 3. Battery life is essential on the laptop. I will get the newertech external charger and one or two spare batteries (hence the MBA is out) 4. I do not play games/video editing, etc. so the graphics card isn't a big deal to me. Advice?
