I'm having trouble deciding which one I want. The main thing I'm worried about is the clarity of volume as I'll be using it to stream media from hulu, netflix, ect. Is the speaker volume the same for both or is there a noticeable difference? MacBook Air 13" refurbs are 1,099 There are no speaker grills but I think there are two speakers and it comes through the keyboard? I keep reading conflicting material, does flash hw acceleration work? MacBook Pro 15" recent refresh is nice only thing is it's more expensive and the AMD graphics don't work with flash yet.
