Has anyone used one of these, like http://www.ebay.co.uk/itm/271548040270?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649?
About 5 years ago I had similar (run WindowsMobile OS) unit in my Laguna mk2. I wasn't happy with screen quality (poor resolution, colours and angles), also touch screen was far from what you expect from tablet/smarthphone. The worst news was that DVD drive broke down after 5 months and it wasn't possible to fix it as it was "one use" device from China. I would rather go for 4 times more expensive system branded by leading company.
