From what I can tell, Toshiba took a beating on the Thrive because of its bulk, both thickness and weight. It seems that at the least, Toshiba dumped the full size USB and HDMI ports from the Excite design. But what about the replaceable battery option? My guess is that also went away but I am not sure. Given that my Xoom battery is already not lasting as long as when new, I'm getting about 6 hours of solid use instead of 1 day plus, I was pretty excited about this option in the Thrive. While the Thrive is too outdated to consider any more, I was hoping Toshiba would carry through this aspect on upgraded models. I could not find a site that gave a great break down between the differences between the Thrive and the Excite. If someone had that I would appreciate it.
