After plenty of thought and research I have pretty much narrowed it down to two choices, the base 13.3" MacBook Air and the base 13.3" MacBook Pro. I have completely ruled out the 11.6" Air and the larger Pro models for various reasons. The computer will be used for internet, email, music and occasional photoshop and lightroom editing (nothing really major just casual). I think either system I listed will do the job but I am more concerned with what will be more bang for my buck and more "future proof" if you will. I am heavily leaning to the Air but the only thing that concerns me is not being able to upgrade the RAM if I want to. Is 4GB going to be enough for 3-4 years? I think it will, but I wanted to get others opinions on this. Also, the 500GB hhd on the Pro is nice, but I don't think I need it. The MacBook I have now has a 60GB hdd and I am doing just fine in regards to that. I know new models may be coming mid/late this year but I am in need of a upgrade. I am currently running a original white Intel Core Duo MacBook. 4GB RAM, 60GB hhd. I can run Photoshop and Lightroom just fine on it but this computer is on its last leg. The keyboard stops working from time to time and I need to reboot, files on the hard drive are renaming themselves and occasionaly the computer just shuts itself off. I do not think it will last much longer so I am ready. So what do you guys think? 13.3" Base MAcBook Air or 13.3" base MacBook Pro?
