I really am on the fence between the two. I plan on getting 8gb ram and I only need 128 gb SSD. So my question is, would the 11" air with an i7 and 8gb ram or the 13" with an i5 and 8gb ram virtually perform the same? At that point, would it just be a matter of which screen size i prefer? Thanks in advance. Too bad i cannot get the i7 13" with 128gb SSD
