HTC HD2
The good: The HTC HD2 features a beautiful and massive 4.3-inch capacitive touch screen with multitouch support. HTC Sense offers a more user-friendly and customizable user experience. The smartphone is also equipped with a 1GHz processor and 5-megapixel camera.
The bad: The HD2 is big and might not be for everyone. Speakerphone quality was somewhat poor. It uses 3G support on the unlocked version.
The bottom line: The HTC HD2 is simply the best Windows Mobile phone out there, but its appeal could be hampered by its size and the new upcoming Windows Phone 7 series.
I am currently using the HTC HD2 on andriod ice cream sandwich and I am loving it. Great display good in hand even though it is a rather large phone. It is a 3 year old phone now so its a little slow with its 1GHz processor. Decent picture quality and lots of apps that can be bought play store. One major problem with the one is the off / sleep button where some times if you press it it will disable the touch screen when you try to unsleep the device. Something with the buttons on this phone. I had to have my friend redo my android to make the phone work again and it seems to work well now. You can either take the phone apart and fix the buttons or just try not to use the power button the phone works well.
