NTX10,
The 7 has a stable GB OS, so i'm not sure what you are referring to with the beta tester comment.
Gingerbread is stable on the Original Airpad 7 the same way a newborn colt is stable on its four legs. Sure, it can stand up and maybe take a few steps, but eventually it's going to crash.
Random restarts/power offs. "Insufficient Space" error messages when updating apps (despite having plenty of free space). Piss-poor battery management. App incompatibilities. Occasional severe lag in the touchscreen. Severe overheating. Frequent "Process Has Stopped Responding" messages.
Granted, some of those probably have more to do with poor hardware design than the OS, but surely some of that can be resolved with software fixes if ICS is adapted to the tablet correctly.
At this point, I really don't expect a version of ICS. Why bother from the manufacturer's perspective? There will be a day soon when I raise a lot of hell (demands to "customer service" for a refund, contacting the BBB with screencaps of their posts promising ICS before I bought it, etc.) Honestly, not having ICS isn't a HUGE deal to me, but a company promising something and not delivering on it is. You have a responsibility to make good on what you say.
