The MacBook Air is not MEANT to be a powerhouse for geeks, it's targetted at people who want reasonable performance in a very compact form. Apple have *deliberately* stripped out a lot of the unnecessary stuff (unnecessary for its target market, not geeks) to make it so unbelievably thin and portable.
The whining I keep hearing from people moaning about how expensive it is given it's been stripped down. Sorry guys, but stripping all this stuff off a standard laptop form factor takes R&D time, it's the same reason Porsche make versions of it's cars which have everything stripped out (glass for perspex, removal of seats, no air-con etc, right down to the badge being a sticker rather than a metal badge) and cost MORE than the standard versions with all the trimmings. It's a niche market that they're catering for and the design costs time and therefore money.
If you have about £1200 to spare and want an Apple laptop, you have 2 choices - buy a full-featured MacBook Pro if you're a geek and/or want the power and features the larger form-factor provides, or buy a MacBook Air and get the ultimate in portability with some features and performance sacrificed in order to achieve that.
Remember geeks - the MacBook Air is not targetted at you! Go buy the MacBook Pro instead.
