I haven't bought a tablet yet. But if Google releases a Nexus ICS tablet I just might pull the trigger. Been eyeing a Transformer Prime for awhile wondering if its finally time.
I can add my name to the list of taking the survey. Got the call a few nights a ago, and if you don't have a solid 15-20 minutes to spare, don't take the call. I can say they did ask basically everything about the phone. The sucky part is it wasn't a live person but an automated phone call. Most answers are simple yes/no, but there is at least 100 different questions.
I figure the survey is worth while if they take the information and make improvements in future updates.
It was from a live person who quickly identified herself from a research firm. It was not a positive experience. I had the feeling I was frowned upon for not giving the correct answers. They covered almost all the issues listed in this forum. It was also quite long and ended quickly.
