iOS, Android, or Windows 8

[Phail]

I'll go with Android since it's the one I'm using.
I've had a Samsung Valencia with Windows on it but it was crap.
Other than that, I can say Windows on Lumia is pretty damn cool
iOS is shit.

Android in my opinion is best for a phone though I like windows on my laptop windows 7 preferably
