Okay I've started this thread to explain to all the naysayers why Apple made the compromises they did in the MacBook Air (you're still welcome to comment on their other products as well). I won't steal all the talking points from you, but here are some starters: Just look at the top/middle left of the first attached photo (of an aluminum MacBook) to see why Apple forewent putting an optical drive into MacBook Air - it takes up WAY too much space. Apple had to only have one USB port because of the INTERNAL limitations. The only way they could add another would be to reduce the size of the battery, which would likely be complained about more loudly than the addition of another port would be praised. (See second photo for the size of the battery and logic board inside MBA; the three-port door is in the top left of the snapshot.) The processor in MBA rules. Hands down. If you need proof just look at other "ultraportables" that have like 1 GHz processors. MBA is not expensive, relatively. Again, just look at other ultraportables - they usually START around $2,000!!! (MBA starts at $1,699 for me since I'm military and $1,799 for normal people.) Feel free to add other explanations!
