Oh, you'd love TiVo's new "HD" user interface. The main bug is that it's remarkably sluggish. A secondary bug is that it doesn't handle the arrow-keys in a transparent way to how the classic interface works. And, naturally, several of the newer features, such as the Pandora support, are only available on the HD user interface.

Assuming TiVo got some competent staff, I imagine there's plenty of horsepower inside the new machines to pull off a very nice HD user interface.
