The tablets will be available with Windows RT running on ARM based processors and Windows 8 running on Intel's x86 chips. The lack of Windows RT models from HP off the bat reduces the number of such models available. As it is, Microsoft has limited the availability of Windows RT to ensure that a smaller number of high quality ARM based tablets will be available at launch. The cost of the license to use Microsoft Windows RT also will limit the number of ARM based tablets. Somsak says that the first HP Windows 8 tablets will be focused on the business market.
