I can 100% Agree with scott. If i had $1800 to blow I'd be typing on a Macbook Air. I can honestly say I NEVER use my DVD Drive. I've put in maybe 3 CDs since I've owned it (2 years) and only one was necessary. USB? I use an external drive for time machine and hook up my ipod from time to time, perhaps a printer, none of which are required to be running at the same time.
All of you on here whining about functionality, etc, live and let live. Some people just don't use the same utilities as you, and some people will sacrifice maximum functionality for maximum portability.
Game over, if you don't like it, don't buy the air, and especially don't troll the Air forums.
