Sorry if this question has been asked, but thinking about getting a new laptop for the wife. E-Mail, web-surfing, pretty basic needs. Portability is key. We have a 24" iMac and a 15.4" MacBook Pro for the heavy lifting. Want to keep spend around $1k and keep seeing the 1st gen MBA 1.6 going for $999. Better buy than a new whitebook? Thanks.
