Email Comparison: iPhone, Windows Mobile, Android, WebOS

In this video we compare the email experiences of the major smartphone operating systems (excluding Blackberry). This is a follow up to the Home Screen Comparison video we came up with a few weeks ago. While this particular test is pretty subjective, it's easy to see in the video that the email clients of the iPhone and HTC HD2 are the fastest. Beyond being fast, an email client must also be efficient by reducing the number of screen presses needed to do certain tasks. And finally, rendering fidelity of messages is also important, meaning what you see when viewing a message should be similar to what you see in a full mail client.

What do you think makes a good mobile email experience? Which smartphone platform provides you with the best experience?
