For me, it's not just because it's Microsoft. Hell, I played my 360 more than anything else in gen 7. If Sony decides you have to have the Eye set up at all times with PS4 then I won't be getting that either. It's just a privacy issue. I deleted all personal information from my Facebook profile. I only kept the profile as a way to get in touch with relatives/friends as a last resort. I also stopped using Google for web searches. I now use Startpage, a search engine which gives you Google results without actually tracking your searches.
