Intel and Nokia announced yesterday that they are working together to build a mobile platform.

This will utilize the mobile chipsets to which Intel has increasingly been devoting resources lately. It will be an open platform built on a Linux-based OS, available for mobile devices including smartphones and netbooks.

We’ve heard rumors that Intel was working on actual mobile device hardware (read: phone), though it seemed rather unlikely. It’s clearer now that this will involve a line of Nokia mobile devices built on Intel chips.
