Power and battery life
The XO-4 features a powerful dual-core CPU running at 1GHz or 1.2GHz, 1GB or 2GB of DDR3Â RAM, 4/8/16GB eMMC storage (and larger in the future). It supports a new battery chemistryÂ (NiMH).
XO-4 – HDMI output to monitor
Video output to connect XOs to monitors and projectors has been a popular request. The XOÂ 4 includes a mini-HDMI output port that can drive HDMI devices as well as traditional VGAÂ displays (with an adapter). All in plug-and-play style.
Older XO models still support USB-to-VGA solutions, and the team intends to expand supportÂ for DisplayLink, which is a strong industry standard for USB-to-VGA.
Good things stay the same
In the midst of all these changes, the development team is making sure that all the good thingsÂ of the XO laptop remain in the XO-4 model.
The child-proof grid membrane keyboard avoids choking hazards and has won the onlyÂ â€œChildrenâ€™s productâ€ USL certification in the industry. The power input allows charging from aÂ wide range of power sources, including power sources that vary their voltage such as solarÂ panels.
The team has been careful to preserve the sunlight-readable screen and long battery lifetime.Â The microphone input jack still supports connecting humidity and light sensors to use themÂ for science experiments and learning programming.
The laptops still work in hotter and colderÂ environments than others, and still work at higher altitudes too.
For established deployments, it is also important that almost all XO spare parts remainÂ compatible. Existing and new laptops can trade parts and share parts inventory to protect theÂ existing investment and save money. New XO-4 motherboards can be used to repair or upgradeÂ older units at a very modest cost.
A new release of our operating system is planned for early 2013â€”bringing all the new softwareÂ versions to existing XO laptopsâ€”so environments with a mix of earlier laptops and new XO-4Â can have an integrated user experience.
When you open an XO-4, there are lots of things insideâ€”most of them invisible, hiding in theÂ details. Millions of engineering hours, thousands of sleepless nights from the team, making sureÂ this is the right machine for the next generation. For the next few months, the team will still beÂ busy in at the assembly lines, the test labs, pounding keyboards, making sure everything comesÂ together right on time for the start of production.
