I got my unit this afternoon at BB. My local store had a huge pile of them in one of the locked cases, and I'm sure most stores were equally well supplied.
So far I am finding it to be an interesting tablet but I have yet to be amazed. It's a polished and well-refined design which is easy to hold in one hand between thumb and fingertips, but I do not care for the non-removable bloatware or Google's attitude towards registration. I much prefer a more generic Android experience.
I'm still not sure I am keeping it, but I plan to play with it for a few more days before making a final decision.
