Introduction
For those who are searching the right computer for Trisquel, that has recent FLOSS-friendly hardware, comes with a pre-flashed free BIOS, while maintaining top price/performance ratio; the Acer C7 Chromebook (C710-XXXX) provide one of the best choices currently available. Recommended for home (as desktop, using external accessories), and travel use.

० keyboard may not fit to all tastes
Recommendations
० upgrade kernel to 3.5 and later

० buy an external drive for data backup (get the one with the best price/capacity ratio)
० buy an external bluetooth USB dongle (if needed)
० flash a custom BIOS (to remove the "OS verification" screen, and add SeaBIOS support)
० if you are going to use it at home, an external keyboard, mouse, and a monitor/TV is recommended
