A quiet addition to the relatively new Lenovo S12 grants users a bit of a speed boost if they're willing to sacrifice some battery life to get it.
The option is a VIA Nano ULV 2250 processor with Chrome9 HC3 graphics. This setup replaces the usual Intel Atom and GMA 950 tandem that ships normally for about $500.
Incidentally, the new option is $50 cheaper too. [Lenovo via Engadget]
