This month, Hewlett-Packard are destroyed TouchPad after sales languished.

"So far, Apple has many potential competitors face, but none has gained significant market share," wrote Abs. "Not only have the potential to Amazon quickly gain share, but the willingness to sell hardware at a loss, as he did with the Kindle, Amazon makes a bad competitor."

A problem with rivals iPhone was expected that the developers have so far before you make a lot of applications or uses for the devices to create, Forrester said.

Apple says some 100,000 custom-built iPhone, honeycomb, the Google platform, which is the compressed version of the Android operating system, has attracted fewer than 300 applications, says Forrester.
