I have a windows phone and I like it. I basically switched from the iPhone. Thing is, "apple hasn't been the same since Steve Jobs' death. Android I would never own, as I simply can not stand anything google.
Yes: Windows phone doesn't have, "an app for everything." It sure does have an app for most things.
Yes: Microsoft is charging a high license fee, and Windows phone is always going to be a manufacturers second choice to using a free Android.
Do I like my Windows phone better than the iPhone 4 I used to have? Its hard to say. I certainly like my Nokia Lumia better than the iPhone, but I thought IOS 4 was a great operating system. However, as soon as IOS 5 and especially IOS 6 came out, I begin to like the operating system less and less.
My Nokia Lumia is more durable than the iPhone. The Nokia is hard, hi-tech polymer; it doesn't scratch, it doesn't seem to be breakable. The Nokia has a bigger screen, better camera, and better graphics. The Nokia is also way faster, and has a lot less bloat-ware.
Before my iPhone I had a blackberry, and it was great. It was, "my first smartphone," and it was state of the art back then. Before the blackberry I had about 8 - 10 years worth of samsung flip phones; I know samsung very well, and I wouldn't by any more phones from them. I only mention this, as samsung is the biggest seller of android smartphones, and really with both samsung and google, "i wouldn't be caught dead."
