This is an odd development but may be useful for some folks. The guys behind Weaknees figured out that you can interchange the front faceplates of TiVo boxes between almost any series 2 TiVo or DirecTiVo.
One of the downsides of having a standalone TiVo is that if you lose the remote or the batteries die, it's essentially a useless box. But the DirecTV versions always included basic TiVo nav buttons on the face. I've had a couple DirecTiVos for the past few years and from time to time if I'm sitting in front of my home theater setup fiddling with buttons, I tend to use the faceplate controls instead of a remote, but it's not very often that I do it.
Still, for die-hard TiVo fans a new button-filled faceplate might serve as a good backup in case your standalone TiVo remote ever dies.
