It doesn't do it all, doesn't have a Express slot like the MBP, doesn't do gaming anywhere as well as the MBP, doesn't have a backlit keyboard, doesn't have as high a screen res as the MBP, and if you can carry a MacBook you can certainly carry the MBP unless you are a pathetic weakling.
Wait you mean that not all of those things are important to you? Apply some of that clever logic to the AirBook.
1) Ive yet to meat someone who uses express
2) Dont compare a powerhouse laptop as the MBP, that thing pisses all over your airbook and regular macbook. if i were to spend that much money, with the intent of playing games on a laptop, (or not) id get the macbook pro. seeing how most people DONT play games on laptops, because the experience is pretty miserable, and by gaming i dont mean your crappy OS X ports with ****** frame rates, your argument is useless.
3) the high res screen, again, your comparing the MBP, i was not. stay relevant. the airbook doesnt have it either, what are you complaining about?
4) the backlit keyboard....lol, hardly an absolute necessity. why would you even bring it up?
And finally, for logical and rational purposes.....if you can carry any of the mac laptops, you can carry the other two without a problem. if you think the airbook is now the holy grail of laptops because it is so thing and great for your needs, than YOU must be a pathetic weakling.
get real, the ONLY thing that makes the macbook air is its size. apart from that, for that price, the specs are CRAP considering the comparison to a normal macbook.
