Basically this, with the Windows 10 on the horizon and MSFT claiming better synergy across platforms and Windows giving the same experience no matter the device. If I can somewhat seamlessly move from device to device and keep (again somewhat) the same experience, that would be awesome. That's what made me decide to give it a shot. Plus I got the 635 cheap. I like the main screen and the live tiles. Think they look great. I had to check it out. As I said above though, the app gap has killed it for me and will kill this platform unless MSFT and the developers make some changes. One way to do that is to grab people like me and iOS users. To do that MSFT knows they will have to change their UI to something a bit more recognizable to them. I know WP users love their beloved UI as it is but you will love it in to the grave if changes aren't made and more users aren't grabbed. I say a small amount of change for current users to get used to is a small price to pay if more people can be coaxed over to this platform, encouraging more developers to make apps and more companies to support the platform and get other apps to come back. After that maybe get MSFT to allow customization to the point you can choose ... or hamburger and other UI elements you like.
