I'm trying to do research on my tablet decision. The Samsung model has the advantage of a smaller, lighter body. However, the Thrive lets you replace the battery and it has a lot of ports. My question is, do you all really use the ports a lot? What are the good uses for the USB port and others that you can't live without? How long is the Thrive's battery life? If it's like the iPad2, we may not need the extra battery. Is there anything else I should know about bugs and great points about the tablets? Thanks for your help.
