Yeah, I think the Zen was shown along with the Galaxy Tabs when I was looking for a new tablet. I dislike anything lower than 2 GB RAM, so the small tablets are nice and powerful. In terms of overall, if you want something powerful, definitely stick with name brands for good hardware... I don't remember, but this one generic brand was putting in stock genuine hardware... Hmm... Maybe it was the A710... I'd have to research.
Anyway, if you're willing to deal with Amazon's control over tablets, a fire would be nice.
