have you held one? as you say it has a smaller footprint, but it's only .5 lb heavier. that was what actually turned me to the 11" MBA... the 13" MBA just felt like a really sleek laptop to me, i wanted an ultralight...
now, spec for spec i think the 13" MBA is a better deal bang for your buck wise but the rMBP is perfectly portable
Yes actually. I know what the weight is, it just felt denser than it should for its weight.
