Pocketnow has been doing a great job of showing us the differences in the 3 hotly debated devices, iPhone, Windows Phone 7 and Android. In this video, he uses iPhone 4, Windows Phone 7 (not official) and Android 2.2 (Froyo) for the email client comparison.
In my opinion, if you want a work phone, the Windows Phone 7 seems like a better choice. However, knowing that everyone is using the phone for everything, I hope that Microsoft will or continue to look at the development of interesting apps.
The take up rate (or lack of) of Windows Mobile phone should serve as a reminder of what consumers wanted.
Now, enjoy the video.
