Chromebooks are generally affordable devices but they might be even more pocket-friendly with the use of a low-end chip. MediaTek has contributed code to Chromium operating system (the base for Chrome OS) to test a device running on an entry-level ARM Cortex-A7 processor. Theoretically, this will create Chromeboxes and Chromebooks that would cost less than the usual US$200 price of these devices. However, this will also affect speed as the Cortex-A7 system can be quite sluggish. MediaTek has not said what they plan on doing with the code but this is just showing us what may lie ahead.
