You can pick up a Chromebook for a dirt-cheap $200, if you know where to shop. However, there are now signs that these Google-powered portables could get even cheaper. MediaTek has contributed code to Chromium OS (the base for Chrome OS) for a test device with an entry-level ARM Cortex-A7 processor -- a big step down from the relatively inexpensive Cortex-A15/A7 hybrid that Samsung uses, not to mention the Intel Celeron chips in other Chrome devices. Theoretically, this leads to Chromebooks and Chromeboxes that cost significantly less than $200, albeit after a big speed hit. Just as with phones and tablets, a Cortex-A7 system is likely to be pretty sluggish.
