This is interesting. I'd argue that while vaguely true, this is somewhat irrelevant. If you look at the "rival brands" you'll see that most of them produce Android tablets. So while the hardware guys will all have a very difficult time "dominating" the tablet market, together they all build basically the same ecosystem together, with Apple in a different world. Since the Samsung tablets run the same OS and applications as the HTC and Motorola tablets, I think the more informative information about consumers desires would be a graph of OS mindshare: do you want an Apple OS or a Google OS?
Actually, both matter. These charts almost always show 1 side or the other, but it does matter both ways.
On the Apple side, there's no decisions to make, and upgrade paths are very clear.
On the Android side, there's plenty of options and it's a very competitive market. If you don't like the current offerings, 3 months will see a bunch of new devices.
Upon HP's release, the top three brands known to consumers in the US in the tablet market will not be running Android. Samsung is the best known of the Android unless Sony decides to show up.
