I have one and I like it but I too am probably going to switch to Android with the next phone I buy (which may be sooner rather than later, since the USB charger seems flaky now!)

The app selection is really, really surprisingly bad. Not just for the popular missing apps (snapchat, etc) but just about anything has a ton of dreck, and if you're lucky one or two functional ones.

I'm pretty surprised at how badly Microsoft has courted app developers on this platform.
