As a result of this, new tablets that move away from Apple's established tablet-standards result in poor interest. According to Bernstein Research:
We find that consumers are not interested in form factors that deviate from the benchmark set by Apple. Few consumers, less than 15 percent prefer the 7″ screen size versus the 10″ screen of the iPad . Over 50 percent of respondents are firmly in favor of the 10″ screen, which leads us to conclude that the 7″ tablet models recently launched, like the Blackberry Playbook, are destined for failure. Consumer’s preference for the 10″ form factor explains the lukewarm response to Samsung’s 7″ Galaxy tablet and the rapid introduction of larger screen models in that series.
It's unsurprising that Apple is ahead of the competition in the tablet market, because the company effectively reinvented the tablet computer as we know it. As far as the consumer is concerned, the tablet is the iPad.
Bernstein Research has predicated one of two possible outcomes to this situation. Either "tablets remain a premium market" (dominated by Apple), or the market polarizes, resulting a "premium" end (Apple) and a "fragmented lower-end." Personally, I'm not sure which I'm expecting to see.
