I was looking around on google and found that the Coby Kyros MID7045 had the longest battery life. It said 48 hours but when I came here people were reporting different fingures. All I really want is a tablet that I can read my pdf books off and it have a mic. I do need some storage space for the stuff I will be recording. It needs to have a long battery life. Cheap is nice but not a big deal if it has a long battery life. Thanks for any feedback!!!
