Exactly - I expect you are right in the same spot as the rest of us. What I'm wondering about, as I have my MacBook sitting on my chest while typing - is how/will we type into the MacTablet so I can make posts like this one? The MacTablet will likely _nail_ eBook reading (And I say this as a Kindle, K2, and Kindle-on-iPhone regular user), Video (over 200 iTunes videos, mostly TV Shows, purchased in the last three years) and, of course, web browser (though flash is a wildcard)
There may be some _new_ sweet spots created though - the one that comes to my mind - Photo Management/selection/uploading - Something fast, light(er) and easier than a MacBook to pair up with my EOS 7D would be nice. I'm just _praying_ that it will take a USB-GSM/1xEVDO wireless connection so I can use my existing USA(Sprint 1xEVDO) and Canadian(Bell-GSM) connections.
