Hello, I am a student in college pursuing my Bachelors of Science in Business Administration - Human Resource Management. I had a Dell XPS 14z, which is toast and I want to move to a Mac now that I have a reason to. Here is what I liked about my Dell XPS 14z: Long battery life for what it was Backlit keyboard Fast Build quality was nice, but nothing close to what a Mac's is It had 6GB RAM, a core i5 processor (3rd generation), intel integrated graphics HD 3000 (I believe it was 3000, but may have been 4000). The screen was 1368x768 I believe. I am interested in the cMBP 13 or the MBA 13. What I like about each is: cMBP 13: Upgradeable (RAM/HDD/SSD/Battery) CD/DVD drive (don't use it often though) Nice build quality, feels very sturdy MBA 13: Battery life Most up to date specs when compared to cMBP 13 Light and portable My main concern is longevity of the system. I want a system that will last at least 4-6 years before needing replaced entirely. I know some people who have had cMBP who have had them since unibody has come out and even some who had old PowerBooks or White MacBooks who still have them and have had no issues with them. I know the newer MBA and rMBPs are not really user serviceable now, however. Any suggestions on which model to go with? Thanks a ton guys!
