Hi
I got my TC30 from a online store i New York ( I live in sweden)
Yes- the buttons are rubbertype. exept volume, channel, glow, navigation, activitybutton and the screenbuttons
They are glowthrough as you wished.
The non rubber buttons feels very goot too.

Rex Diamnd: I managed somehow to get in to logitechs configurator, and there I could change settings so I got one activity/device per line. I also got diffrent icons when I did this.
I only got it to work with IE (not firefox that I usually use)
Dont know if this work, but its worth a try.
Plug in the remote in the USB port of your computer
Go to logitechs loginpage and login with your harman kardon username and password.
You will be redirected H/K´s site.
Close the window (dont logout)
Then go to this site (logitechs "test drive" site for harmony) test drive
Now you should be able to edit the settings you want.
It works fine for me. Good luck!

Akirby: I would say that the TC30 is based on harmony 880 but in a
520 lookalike casing.
