I would submit feedback, but for that I'd have to have enhanced or full data being sent back to MS, and I specifically set that as low as possible (basic), which then won't allow me to use the feedback feature.
I did make a post on MS's support forums about the issue, as it is now occurring very often, though not every single time. It also tends to lag a lot when resuming from hibernation (as in, I resume, log in, and open any program and try to type and the keyboard won't work. If I'm lucky, it starts working within 10-15 seconds, but IMHO, this is unacceptable).
