Don't forget that the RC9800i supports UPnP and the Harmony doesn't. If you want to use the device to control content on a PC (which I'm guessing you do based on your listing of Creative Jukebox in your equipment list) this will be amazingly useful. While viewing pictures on the remote control may not be that useful, being able to browse and control your music collection from the remote is pretty nice. This is a pretty nice feature to get at the $500 price point.

If you don't care about being able to design the remote yourself and just want all of your equipment to work with one remote, I'd definitely go with the 9800i; it's also a lot sleeker looking. HTH.
