I haven't seen the keyboard problem. The main one I saw was a disappearing mouse pointer, which was fixed by removing and re-attaching the keyboard. Weird.

You could try a software reset for the performance problems, bearing in mind that the updates will drive you mad. Unfortunately you can't fix the slow CPU or the too-small RAM. However, the current performance should still compare reasonably with another 2012 tablet.

Look out for Windows 10 on the Snapdragon 835 later this year ;-)

Yes, I bet that hurt, even when you have the odd $100 billion in spare cash.
