MacBook Air. Aside from the regular list of MacBook accessories, you'll have to decide if it's worth $300 to go from a 1.6Ghz Core 2 Duo to a 1.8Ghz. The only other choice to ponder is if your also the SSD type. Sure, SSDs are faster and use less power than their spinning brothers, but at $999 -- and 16GBs less capacity -- it's a hard pill to swallow. Of course you can get the ultimate MacBook Air for $3,098 and while you're at it, go ahead and get an all but useless optical drive for $99 and what is almost sure to be a required accessory on any first gen product; AppleCare at $249.
