Do agree with most of the things posted in the OP except for the video calling. Setup 2 googletalk accounts input those credentials into your two tablets. Get network access on both tablets goto >Contacts find your contact and select >internet call... the other tablet will ring, the N810 will automatically launch video, the N800 has to have the little camera pulled out. I use video chat over google with my girlfriend 3G tethering >wifi, works well and works flawlessly. Look into your network setting or something because it does work better than gizmo and is a native application.
