I switched to outlook for the same reason. For now I am trying it out, and so far I like it a lot more. The outlook.com is so much cleaner to me, easy to navigate, don't look cheap looking, and just nice.
I personally don't want to use different email apps for all my email. I like to have it all in one place.
I use .Me as my main email, but I need another one for iTunes. I also liked Gmail and now outlook for the 2 step verification security also which .Me doesn't have (yet).
