Received xo yesterday. Intuitive with a little learning curve. A lot of computer for the money! I got this to carry around to court and for hiking trips. A little difficult to set up sharing with my macs so far. Easy airport connect. Have not figured out how to share documents or backup to my servers so I can print since has no printer drivers. This is an issue for the bogo program which should be extended to US as well. While children in many places will not have access to printers, many will an certainly donors do. Giving the xo to someone to use in an American school (many students underserved) will be hamstrung by no printer access. Cannot find how to switch the screen to low power b&w. battery seems good to 3 hrs in color mode. Overall, "A'.
