I like Windows Phone in General, if you listen to a lot of music, watch a lot of videos, and want something easy to use, simple but also powerful it works very well.
Nokia Lumia 610 is a budget smartphone, however limited you might find it (and I agree with you on that one, but those are mainly restrictions inherent to the OS itself), and budget refers to the price of the phone not to its features (or lack of).
About $120, great phone at this price range much better than any android device that comes this cheap i.e without subsidies.
