There isn't a great story for dropping one more device - the phone. And that story is quite unlikely since you wouldn't want to carry your tablet with you on a night out, etc. I could see myself using this and dropping my phone if I never did things like out of band experiences. I'd eventually have enough situations per year where I wanted my phone, not my tablet, that I'd end up with a phone - but maybe I'd live with a 3-5 year old phone for that...

The wife would not like to see the tablet around 100% of the time since, with LTE, it'd be a physical extension more than PC's and the phone are now.

Well, sure, for a consumer device that I use on my couch in the evenings, I certainly don't need LTE. But the Pro seems pretty geared towards business, right? For business travelers this makes a huge, huge difference, though. And it seems to me that the high end Pro version is probably exclusively targeted at business users, at its price.

I would have bought LTE with my surface pro, had it been offered. My iPad's LTE is so flaky I don't trust it.
