I have the Harmony 890 in my bedroom now and the Harmony One running my main system. My wife definitely likes the 890 better, I like the Harmony One. The 890, as with the 880 has some charging problems with the cradle/remote batter contact design, so it can run out of juice and you have to "jiggle" the remote in the cradle to get the contacts to seat correctly. They are both excellent remotes and very similar.
I have had 3 different Phillips Prontos and didn't really like them. Too hard to program, too expensive, and too big.
I still love the Home Theater Master remotes, and in some ways they are more flexible with programming, but it takes more effort. The Harmony software locks you in a box with some things, it's difficult to write stand alone macro's that don't fit their standard questions given during programming, but it is extreamly simple to use in general.
Good luck.
