I've noticed this problem too, although it has only been since the last firmware update. MS needs to make some adjustments, because it didn't do this previously in any significant way.
I have noticed one new feature with this update. The Band vibrates when you start charging it.
Yes, important tips. I charge mine in the bathroom while showering, getting ready for the day and bed. And that seems to do it for me.
I saw the ad on TV on the weekend, but the closing title actually said "Surface RT" instead "Surface". This won't completely eliminate confusion, but it is more accurate.
