This is more for the techie types I think. I am thinking about getting one of these 4" tablets and permanently mounting it in my van. I will get also get Raspberry Pi and link them via wifi. Due to the built in IO ports I can them control anything in the van via the android tablet. Just after christmas I will have my motorhomewifi.com 3g/wifi router set up so the van will be comprehensively networked:thumb: I will configure the tablet to give me local weather wherever I am, temperatures from 2 digital thermometers one inside one outside. I will be able to control the lights. I will setup news feeds, email notifications and server monitoring. I could also link in external cameras for additional security when wilding. So many more ideas as well. £49 for the tablet £35 for the Pi Probably no more than £20 for the electronics. So around the £100 mark.
