I had a Windows Phone 7 and loved it but ended up not being able to afford the monthly payments at the time that was required for having a smart phone. I didn't have much of an app issue but that was because I didn't have the phone long enough. I have a co-worker that also had a Windows phone as his previous phone and liked it. He wanted to get another when it was time to upgrade but he couldn't, there just wasn't any available.
