20 iPad competitors

It's hard to overview the exploding tablet market, but this article, 
20 iPad competitors, makes a brief attempt.

Apple's influence is remarkable. One gets the feeling that if tomorrow they launched a pocket ashtray with wi-fi, by next month, 20 competing products would be announced too.

But of course, it's not because it's Apple. For example their Cube computer from 2000 failed in the market and was not imitated. It's when they do something spectacularly right like with iPhone, iPod, or iPad, that those explosions happen.
