I hope you take some time to add in ALL the features of Gmail. FILTERS. FILTERS. FILTERS. Why the hell can't I do filters from a phone?
And, while I'm at it, make it freaking faster (and easier to use) than simply going to http://www.gmail.com
Why do I need to click to load new email? That's lame.
The bar is high for apps. Make it better than a web page or DO NOT RELEASE! Please.
