There are Intel based Win8 tablets with an Atom processor for sale now. Acer, ASUS, and Samsung have some out now. I believe Lenovo was coming out with one too, but I’m not sure if it’s for sale yet or not.
I was just given an ASUS one, but it doesn’t have a dedicated USB port. I can use a converter to the power adapter that turns it into a USB port, but I don’t know whether the OBDII port will provide power to it through the VAG-COM cable. It does have a keyboard base though with dedicated USB ports that can be used with the tablet.
I have the Samsung one at work and know it has a dedicated USB port. Microsoft will be coming out with Intel Core based tablets in a month or two. Those will definitely run the VCDS software.
I’ll go test it on my ASUS one and if it works, then you can buy any of the Atom based tablets and it will work on any of them since they all have the same CPU and were all created based on the same reference design from Intel.
