I recently opened an Outlook account because I'm finding Google's business model creepy and so far it's been pretty nice. It integrates well with my BlackBerry Passport (switched from Android) and two-factor auth was pretty straightforward to set up. I've moved my entire calendar to outlook.com and I'm forwarding my GMail there for now and hopefully will migrate completely over the next year.
When I started to think about how Google was privy to just about all of my online and some of my real-life activity, it occurred to me they could build a disturbingly accurate profile on me, and while I'm just a boring 30-something middle-class white guy, I still found that creepy. Now I spread my data out between Google, BlackBerry, Outlook, and Yahoo and it's not really any less convenient than having it all integrated (the phone does integrate it all I suppose, but BlackBerry is not trying to use that data to show me ads).
