Hi, I'v thinking about swith to MAC for a while, mainly for the easy of back up and restore (no need to reinstall all programs). The 15 rmbp would be ideal for me but way too expensive. Currently, refurbished 13 MBP early 2011 model is really cheap, but the resolution 1280*800 is just not what I want. The current refurbished MBA is decently priced, I think would work well for me except that I am too spoiled with ipad 3's display, I am thinking of selling my ipad after get a MBP or MBA. Another concern would be the ram on MBA, most likely I will only be getting a 4g model because of the price and availability on refurbished. My main questions is what can we expect from 13 rmbp at this point, especially the price. I would not mind the weight or performance too much.
