It seem that you are more of a patient person than I am ktg. When watching TV I like to channel surf and that might not be possible with this remote. Another thing I came across is that when using activity based controls the remote frequently fails to turn on/off one of the devices maybe due to the lag in the interface?) and you have to use a "fix" button. I know that these shortcomming may be considered minor but I am an impatient person
However, it is good to know that it would work with the XBox360 (any rumors about the PS3?). The TV guide would not be that interesting to me as the XBR2s (SXRD) work with a cable card and have a built-in TV guide so that you can get rid of one additonal (cable) box.
