If you've switched from a Mini to an iPad Air... what are your thoughts?

You're surely used to the great portability of the Mini by now, so switching to a larger device, what do you think of it? Do you miss the portability of the Mini? Do you take your iPad everywhere or does it stay at home? Are you planning on scooping up the rMini and returning the Air the first chance you get?

I'd especially love to see thoughts from people who use their iPad on the go constantly. It'd also be great if you use it for work purposes, but not totally necessary.

Coming from a full sized iPad 3 myself and very eagerly awaiting a Retina Mini for the extra portability, I'm wondering if the Air is light enough (with a reasonably svelte case) to comfortably use on the go.
