I guess the only way to find out about an update, and to apply it, is to connect the remote to your PC?
I've been slowly introducing the Touch into my arsenal. Wife still using the 880 primarily. I think she would like the Touch better, but the one thing that drives me a little bonkers (besides that infernal help button) is the way switching to individual device commands from Activity Mode works. Like, for example, if I want to change the 3D settings on the TV while watching a movie on the HTPC. I'm in the HTPC activity mode, I have to then back out until I see the Device button on the bottom of the screen, select TV, do my thing, then back out several levels until I see the activity selections again. A little clunky. Requires several more steps than the 880 did in that regard.
