I'm shopping for a new computer for university, and I'm considering the MBP 13". I don't do graphic intensive work, so I do not need the retina display. It's not worth the extra cash. However, because I'm constantly carrying around my computer and turning it on and off, I want an ultrabook: something light and fast to boot. I'm thinking of buying the 13" non-retina MBP, but selecting the 256 mb SSD option instead of the HD option. If I do that, of course, apple will drop the HD and optical drive from the machine. Will that get the weight down to 3.57 lbs? If so, it might be a cost effective way for me to get the machine I'm looking for.
