Yeah...mine too, but I am some issues with the Mail app. It keeps syncing with my Gmail - its been doing so for the past 36 hours - though I have about 4 GB of mail on Gmail. It should not take that long, should it? I deleted and reinstalled the Mail app - both on my desktop machine and on the RT - twice. As far as I can see, the issue with the 8.1 RT update had to with corrupting the boot record or some such thing, which would have corrupted the install. However, I suspect, there could also be other minor technical reasons too.
