Too many unanswered questions on the old list. I believe because there was too much mixture of tablet types. So they finally broke it out into separate Android, Windows and IOS sections.
So I'll get it started.
I've owned several tablets. Most of them junk. But notable ones have been Acer Iconia A100 (two broken ones right now), and now Samsung Galaxy Tab 2 7.0. I prefer 7" tablets because they sit perfectly in the leg pocket of cargo pants. Looks like Apple has discovered that, too. I doubt Microsoft will last long enough to make one, or to make one that sells.
I rooted one of my Acers to get linux installed. The one that worked left me unimpressed It runs a VNC session, not natively) and another one didn't install. I thought I'd upgrade, so I installed ICS (before it was officially released to me), rooted it again and tried to install that one (Bohdi) again. It still failed. Then I dropped the tablet and now it locks up a few minutes after booting. The other Acer was my son's. He broke the screen. (I intend to Frankenstein them into one good one as soon as I can get the cases open. I've seen demos, but the case is still fighting me on the only one I've messed with.)
I got the Samsung, rooted it and installed Cyangenomod(sp). It got locked in a boot loop first boot. When trying to recover it I got a tablet that wouldn't run anything from Google. Great, an Android tablet that doesn't run Android. At all. I finally found a ROM that got it working OK again. There are some apps missing now, but the only one I miss is a Samsung remote control app. It's not in the market. There is one, but it doesn't work the same way as the original. I haven't given up.
OK. Now we have a topic.
