I think you'll like the new user interface for the iPad. The UI will work in both portrait and landscape orientations.
This update will be submitted to the App Store for review within the next few days. Here's a quick screenshot.

Looks like some folks are having some external keyboard issues when the virtual one is minimized (showing the fake blinking cursor). We'll see what we can do to get it fixed for the next update.
Workaround:
Please leave the iPad virtual keyboard up when using an external keyboard until we get the problem fixed. Thanks for your patience.
