I've also been using a Nexus 7 as my primary (though not exclusive) connectivity device. Instead of GrooveIP, I use Spare Phone, which has a nicer icon (and yes, that is why I chose it). The biggest drawback I've encountered is that talking over the speakers doesn't work well because the other party can hear his/her voice on a slight delay. The other thing I've been really surprised by is how much I like using it to write. Now that the stock keyboard has swipe input, I spend about 1 or 2 hours a day writing in Google Docs (err... Drive). To be fair, I was never a particularly fast typist, so I didn't notice the impact to my speed, that others surely would. Still, I don't find the tablet interface to be much of a barrier to getting my thoughts recorded, which was a real surprise.
