I need something I can leave in the glove box of my car, so size is an issue. It has to run windows as well. I'd be using it 90% of the time for just the purpose I'll list below, so although wi-fi and other things would be nice, they certainly aren't necessary. It does not have to be new...if I can find a used one of whatever you suggest for cheaper, great. I'm going to tune my car on both pump gas and E85. The issue is the tunes will be very different and I need something windows based to run the program that allows me to connect between a USB port and the OBDII port on my car. I'd love to just have a windows mobile based phone and use that, but for obvious reasons that won't work. I have an EEEPC already actually. And I've considered using that. I think it would actually work well if I can load windows onto it. Thoughts?
