Intel believes that Windows RT falls short of the full Windows 8 experience, with a senior executive telling TechRadar that compatibility with old software and peripherals will remain a key issue for the ARM-based version of Microsoft's new operating system.
For the first time, Microsoft has made its Windows OS available on a platform not based on Intel's longstanding x86.
And to rub salt in the wounds, Microsoft has opted to make its own tablet that uses ARM architecture and Windows RT, with the Surface a key new player in the market.
However, speaking to TechRadar, Karen Regis – Intel's director for Ultrabook marketing strategy – explained why the chip giant was comfortable that more people would opt for Windows 8 than Windows RT.
"With Windows 8 you're going to be able to take your whole library of software that you have invested in over the years and port it over to your new system," said Regis.
