So, my GPS died, and I'm looking to replace it with a 7" tablet. I don't want to pay for a data plan so I'm looking for a true GPS enabled tablet. Just looking around, it seems like a good bet is the Lenovo IdeaPad A1. The only thing holding me back is the singlecore processor. Do you have any other suggestions? The kindle fire or the nook color/tablet wouldn't work as a GPS, correct?
