I got mine too, this is my third windows phone in a row. I feel that the OS itself is a bit rough still and needs several rounds of updates. I don't have confidence that the phone is keeping me informed about messages and emails, as I have noticed several times the tile counters to be out of sync with the actual contents of the folder. I also got few spectacular crashes so far and attaching the phone on the Continuum dock was a painful experience, only few apps work and whole system functioned poorly.
Anyway I had similar feeling with the Lumia 800, but it got fixed into nicely working phone. I'm expecting this to start working as well.
