The XO design was a priority from the beginning. The laptop could not be big, heavy, fragile, ugly, dangerous, or dull. Another imperative was visual distinction. There is no confusing what it is and for whom it is intended.
The integrated handle is kid-sized, as is the sealed, rubber-membrane keyboard. The novel, dual-mode, extra-wide touchpad supports pointing, as well as drawing and writing. The laptop has rounded edges and because of the flexible design and 'transformer' hinge, the laptop easily assumes any of several configurations: standard laptop use, e-book reading, and gaming.
The XO is fully compliant with the European Union's RoHS Directive. It contains no hazardous materials. Its LiFePO4 or NiMH batteries contain no toxic heavy metals. In addition, it features enhanced battery management for an extended recharge-cycle lifetime. It will also tolerate alternate power-charging sources, such as car batteries.
Experience shows that the laptop components most likely to fail are the hard drive and internal connectors. Therefore, the XO has no hard drive to crash and only two internal cables. For added robustness, the machine's plastic walls are 2mm thick, as opposed to the standard 1.3mm. Its wireless antennas double as external covers for the USB ports, which are protected internally as well. The display is also cushioned by internal 'bumpers'.
The estimated product lifetime is at least five years. To help ensure such durability, the machines are being subjected to factory testing, as well as field testing by children.
