i also have an m100 and was pleasantly surprised with the range i get out of it. when i first did some reading on using the palm as a remote i was led to believe i could only get 5-8' out of it. mine works in daylight with the blinds open 20' across the living room and so far has learned any remote i have pointed at it, including 3 tv's; 2 cd players; a cable box; 3 vcrs; a harmon kardon a/v receiver; the big screen at the sports bar and a furby.

the only problem i have found is that the flip cover of the m100 becomes a nuisance when using as a remote, especially since omniremote lets you program the hard keys on the palm to do simple stuff like volume up/down, track ahead/back or power on/off even if the palm is off. which is ideal if you really want to use it as a remote, not a palmpilot.
