Yes, I am currently using XO 1.75 laptop to write this blog which needs more update. I am really busy outside Fedora world while waiting for the infrastructure for Fedora 21 in order to refine Design Suite.
This XO 1.75 has interesting apparently unavailable on most mobile device, a type of sensor that turns off the back light from the screen in plain sunlight. Surprisingly other device seems lacking that feature. That will be a useful information for demonstrating the XO Laptop in local cafe as requested by my friends. I guess I will need a touch screen XO 4 laptop because of frequent question of touchscreen support, a trending norm in portable industry.
