I have the 02 XDAII Orbit. It's a rebranded HTC Polaris.
I like windows phones. On my 4th! I had two samsungs in between.
Sure, they aren't as slick as Iphones but they don't have the Apple Marketing man touting them either!
Try them all out. The Iphone is the 'coolest' to use for a few days. However you can upgrade your windows phone to work like an Iphone too without it's short comings (MMS, Bluetooth etc)!
