Intel announced their newest version of the education-focused budget laptop (netbook, really) called the Classmate. It's not the cheapest netbook around, but it's packing some features that definitely endear it to the education market more than your bog-standard Atom-based machine.
Intel's first Classmate PC followed in the footsteps of Nick Negroponte's One Laptop Per Child XO PC by being a similarly cheap, robust portable PC intended for educational use. Last year Intel upgraded the specification to the Classmate 2, but it's taken until now for a machine to surface. It's produced by CTL and it's essentially a pretty snazzy convertible tablet format netbook with a built-in carrying handle.
