I guess I'm behind the times, but I doubt it I'll ever spend $799 on a remote. That's exactly the MSRP on the Sony RM-NX7000 Touch Screen Remote. CNET has a review that states:

In many ways, the RM-NX7000 is Sony's answer to the more expensive Philips ProntoPro NG TSU7000 ($999), also known as the RU980 in Europe. But while Philips encourages the user to dive right in and customize the Pronto, the RM-NX7000 is designed to be programmed by a trained A/V installer. In other words, don't try this at home unless you have gobs of patience and some experience with complex remotes. And since the RM-NX7000 is a relatively new device, it lacks a user community supplying the homebrew graphics, custom keys, skins, and codes that are staples of the Pronto.

If you're seriuos about your remotes and willing to spend a little cash, you may want to take a peek at the Sony RM-NX7000.
