Found a couple nice features using the TP with a Bluetooth keyboard:

1) Pressing the escape key from within any application or the home screen displays the active notifications. This feature is really handy with the weather dashboard, tunein radio, anything with controls in the notification area, etc.

2) I have an eject button on my BT keyboard, pressing it is the same as pressing the home button.

I am using an Apple Bluetooth keyboard. The small aluminum one with 2 batteries.
