iPad + Keyboard or MacBook Air?

Ben Brooks:

The question then becomes: do I take the iPad 2 and keyboard on trips, or the MacBook Air and iPad 2 (since I can’t seem to leave the iPad behind)?

I really don’t have a good answer to this. My mind tells me that, logically, I can do most everything I will want to do with just the iPad. My heart though can’t stand the notion of leaving behind the MacBook Air.

I struggle with the same conflict every time I pack up to go somewhere. I am hoping to pick up an iPad case with a keyboard built-in at some point to see if I can rely more on my iPad.
