Really? MS isn't recording every move with messenger, Skype, One drive and office 365 all being part of PRISM? You think Bing and IE isn't doing exactly the same???????
The only difference is Google make money from spying (and probably report on the spying), and MS is just openly one of the creepy brigade.
I like the feedback idea, but should be proven to work. Has any of the feedback been taken up I wonder. I mean what good is the tiles on the start menu if it doesn't actually allow personalisation.
