To resume the comment Rosiers which is totally false, everything is replaceable top, 2 memory slot, an mSATA port, and it is even possible to replace the wireless card! For the installation of another bone is quite possible by activating the dévellopeur mode, which provides access to install ubuntu or windows to ubuntu there is a script called ready-EyeCreate ubuntu- install! this device is intended for both novice users and advanced users who want more than ChromeOS and all at a reasonable price! then Mr Rosiers before commenting an article find out!
