Guys,
If you are based in the UK and looking for an ideal 7" touch screen remote control, may I suggest the HP Stream 7 which is a Windows 8 based tablet with 1GB RAM and 32GB System storage.
I have just finished installing Grasshopper on mine and will be mounting this device to the wall shortly. This device is currently available at www.pcworld.co.uk for ?99.00
If anyone has any mounting suggestions it would be appreciated, I can advise that to power it, it does use the micro USB format.
Regards,
Mike
