Intel sits in a pretty dominant position in the chip making business, with the exception of one sector: mobile devices. For smartphones and tablets ARM is the market leader due to its low power, high performance chip designs working so well for those form factors.
Intel hopes to change that with the introduction of the next Atom chip, codenamed Clover Trail. But even before the Clover Trail processors are available, Intel has limited the market for them by stating Clover Trail Atom chips will only work with Windows 8. In other words, they won’t run Linux and Intel wont support them running Linux.
