I only recently have found the need for a "beefy" remote with learning/programming features, so I got the 2104, Radio Shack's apparently top-of-the-line model. Now that I have it, I think I would have been better off looking around for a 1994. The "home theater" mode is a good idea (arranging buttons into "groups" and having a seventh "device" which uses buttons from other devices) but in practice I find I still need to switch devices far too often. Plus, in the home theater mode, the "smart keys" aren't programmable to anything. The 4 "favorite" keys are equally useless, and I don't think those can be mapped to other functions in *any* mode unless there's some special tweak I haven't found on any of the 15-1994 hacking sites.
In other words, they oversimplified it and used up valuable buttons for gimmicky newbie features.
