You certainly can get netbooks with 9h battery life. http://www.compuplus.com/ASUS-Eee-PC-1015PED-MU17-1166505.html http://www.compuplus.com/ASUS-Eee-PC-1015PED-MU17-1166505.ht... for example. GPS - when I can get a standalone satnav unit for $70 with its own processor, screen battery et al, that's hardly adding up to a huge extra cost. The accelerometer and gyro can be handled by a single relatively cheap chip from what I remember. Netbooks also have keyboards, touchpads and extra interface parts such as USB and SVGA that tablets don't tend to have - not expensive components in themselves but extra parts to integrate into the design that aren't supplied with tablets. And, in a large number of cases, they come with a Windows license. So, we're left with an SSD rather than HDD (retail, marginal cost about $70 for bigger drives than tablets use) and a touchscreen rather than a non-touchscreen (don't know the component suppliers for them to research it). I still don't see why they're so much more expensive, beyond 'because we can' novelty value. The numbers simply don't stack up for me.
