Well, I've just gotten all the parts together -- the palm personal and the IR upgrade, and installed the trial version of the omniremote software.

Observations:

1. Range of that combination does not begin to match the range of the Cinema 6.

2. The screen is too small to enable the flexibility that the Cinema 6 has.

3. The screen is too dark to read easily, with or without the back lighting on.

Bottom line: skip the Palm, get the Cinema 6 or 7.
