Hello people, new guy here. I am interested in buying a macbook. This would be my first apple computer and i'm in need of a laptop. I do coding and sys/net-administration. I cannot afford buying the 15" MBPr. I wish to have portability along with Pro specs and i would prefer if it had upgradability. I think that the best match for my needs is the 13" MBP but it has low resolution(1280x800) even lower than the equivelant 13" MBA(1440x900). Also in recent rumors the MBP 13" will propably be upgraded with the retina display in October. So my question is, should i go for the current 13" MBP or should i wait? Will the current 13" MBA do the job for me instead? Thanks!
