Does this exist in the Android world?

Is there a skin (CM7 or one of the junky over-the-top manufacturer skins) or apps in the android market that allow me to get the same functionality as my jailbroken iPhone? The biggest features i'm interested in are the following:

- View and respond to text without unlocking the device and going into the app.

- View upcoming calendar appointments from the lock screen

- view previews, delete, and respond to emails from the lock screen

Those are about the only features i haven't been able to find for android that i really enjoy on my jailbroken iphone. I really want to make the jump but that quick access to that information if very important for me.
