With so many new cheap tablets coming out I am interested in getting a tablet to use in the car. I am interested in having Offline GPS Navigation, connect to ODB2 to see car performance, and just have documents, music, some videos on me in the car. Has anyone else done this? Can anyone recommend a Tablet or MID? Any car must have apps? I am pretty familiar with Android and have a Samsung Spica sunning android 2.1 but screen is very small and I don't want a phone as an in Car computer. So far I am interested in the RAmos W7.
