Thanks for the replies, guys.
I also didn't consider the other "Galaxy Perks". The Go-Go and Sirius XM perks have a little value to me too. While I missed the hell of a deal $250+$50 GC a few weeks back, comparatively speaking (edit: with the 7) I'm probably only looking at about a $75 difference in the end. It would be nice if I could find one for sub $300.
Rooting and knox-ing the Pro would be a given but just like my Galaxy Nexus, the dev support seems to be focused on the N7 - not so much the Pro. With 6 months left on the official support of the N7, it's hard to tell what device will last me longer. In the end, I'd be upgrading devices sometime next year probably.
Is the battery life manageable? I'm used to being tethered (or having 5 spare batteries around) with my Galaxy Nexus but still battery life is a concern. At the same time, I don't really plan on relying on this thing having both a phone and a computer handy 99% of the time.
Once again, thanks for your thoughts.
