It should be noted that tablet computers have not been popular outside limited niche commercial markets, such as for medical staff. The tablet computer would have advantages for education, being able to customise the virtual keyboard four different languages and different topics in software. However, it comes at a cost, with the virtual keyboard taking up one third to one half the screen (depending on its use in landscape or portrait mode). The virtual keyboard will use much more power than a real keyboard and also cost much more.
The screen of a portable computer makes a significant part of the cost. An alternative design would have a screen taking up half the body of the computer and a rubber membrane keyboard (as used on the OLPC XO-1) on the other half of the keyboard. The rubber keyboard would cost less and also use much less power.
The XO-3 assumes the use of a flexible screen and flexible circuit board. These are relatively new technology for computer building and therefore the cost of manufacture will be initially high. An alternative design would use a conventional rigid screen and circuit board. The screen could be protected by a thick plastic sheet and a rubber ridge around the edge. The computer could be made without a conventional chassis, consisting of instead a molded rubber waterproof case (the front of which would be the keyboard) holding the components. This could use existing conventional components from netbook computers and use calculator construction techniques for a very low cost computer.
• XO 3.0 – The XO 3.0 is a totally different approach, to be available in 2012 and at a target price well below $100. It will feature a new design using a single sheet of flexible plastic and will be unbreakable and without holes in it. The XO 3.0 will leapfrog the previously announced (May 2008) XO 2.0, a two-page approach that will not be continued. The inner workings of 3.0 will come from the more modest 1.75. ...
