The Lenovo IdeaPad S12 just started shipping last week, and it looks like units have begun to arrive -- the folks at GottaBeMobile just posted up some quick impressions of their review unit. Sadly, it's sporting Intel GMA 950 graphics instead of the NVIDIA Ion chipset that's available for $50 extra, so it runs pretty much like every other 1.6GHz Atom machine with 1GB of RAM in the world. Hopefully those Ion units will arrive soon -- in the meantime, hit the read link to see how the S12 stacks up against the S10. (Hint: it's way bigger.)Filed under: Laptops
