Give it up MS. I. Just. Don't. Care.
Maybe, just maybe, no-one will like the Windows 8 interface and the the big vendors will notice, and start selling more PC's with some flavor of Linux pre-installed.
I've used two Windows phones. Both sucked. Slow, buggy, locked down, locked up. Android for phones and tablets works great. More features than iOS at half the price. I run Linux on all my home PC's and do everything I need.
MS should stick to hardware and give up on the software market.
