I had a job once that issued me a Nokia Windows phone and I was stunned by how much I actually sort of enjoyed the experience. Granted all I did was check emails, ACK alerts and message coworkers on it, so admittedly a very intentionally on my part pared down user experience. Sadly Windows phone didn't last long enough to figure out if that was the result of Microsoft, or the result of Nokia.
Like the other person said...
Had a warranty issue with a Samsung a few years ago that kept it out of my hands for a couple of months, bought a cheap and nasty $50 phone that was part of a prepaid package here in Australia, just happened to be a Nokia windows phone. It was about the lowest end model you could get....
And I too was kinda stunned how much I liked it.
I went into the experience with a fairly negative attitude thinking I'd suffer though it until my regular phone was repaired.
Yet came out looking it more than I'd like to admit.
So... Yeah... Sounds have been great for windows mobile to stick around.
