I had a very brief play with the touch remote the other week at a Sky stand in the local shopping centre.
Felt bizarre - unless I was getting it totally wrong, it appeared you needed to swipe right to progress through the menus and left to back up which felt completely wrong as the action of swiping right moved you further to the right in the onscreen menus which is backwards, or am I missing something?
Do you get another, more normal remote with buttons?
It is a bit naff with the swiping, horizontal across screen is fine but scrolling up/down through the program guide gives you thumb ache using one hand. Two handed operation is self defeating in my opinion. I think it's a bit of a gimmick.
We got two with the silver box, normal/touch and a normal with the mini.
