Well, first and foremost, for the regular consumer, the iPad+keyboard combo will be *much* cheaper than a MacBook Air.
But in terms of usage, I have an 11-inch Air and an iPad+keyboard, and I find the latter to much more enjoyable these days. The key for me: one app, one screen. Yes, there are notifications, but with iOS 6, you can easily silence them for a set period of time and just work, read, etc.
This combined with the touch element actually makes me feel more productive when I’m using the iPad. I definitely prefer doing email on it (again, with the keyboard). With several other apps, I’ve mastered the touch UI far better than I ever have a desktop experience. And several native apps just *feel* faster than their web-based versions.
As much as I like the 11-inch Air, I can’t get past the battery being significantly worse than the 13-inch Air. It’s basically two full hours worse. For that reason alone, I couldn’t recommend it over the 13-inch. And the iPad battery blows all MacBook batteries away. Another huge plus.
So while it’s a close call between the 13-inch Air and the iPad+keyboard, I have to give the edge to the iPad right now. I realize many people will disagree, but it’s working great for me.
