Hi,
I looked at the Dign case to but decided not to buy it because you want to place the case between your other Hifi stuff. So you're touchscreen will not be a handy height. In most case you will have to kneel to touch the screen. That would be bad for a case of EUR599.
I bought a seperate 7"touchscreen and that works pretty good with the normal skins. Even my girlfriend uses it now
The touchscreen and TV are setup as 'clones' so they will both show the same information. A dual screen option for MP would make this even better. I think people are busy with this.
