I'm an iPad/MacBook Air man
Well, my goal of using my iMac as my main computer and an iPad with a keyboard as a secondary system for writing articles, checking email, etc., just never panned out. I simply missed having an Apple laptop when I was away from my iMac for an extended period.
Using an external keyboard with my iPad worked okay for short articles, brief email responses and the like. But when I'm doing my daily workload -- which involves jumping between Pages, Mail, Safari and iCal, among other apps. The iOS just isn't up to snuff for that just yet (we'll see if iOS 4.2 changes my mind).
But I do love my iPad. So now I own it and an 11-inch MacBook Air (standard except that I sprung for the 128GB solid state driver rather than the 64GB model). I use my iPad for media consumption (surfing the web, watching videos, reading ebooks, etc.) and my MacBook Air for creating (writing articles, doing research, responding to email, etc.).
