first bamboo laptop, we raved about more than just its unconventional looks -- we were also impressed with its solid performance. So we're pleased, although not at all surprised, that ASUS is refreshing the line with Intel's latest Sandy Bridge processors. The U43SD doesn't appear to stray from its predecessor's industrial design (save for its bigger 14-inch screen), but it steps up to the latest Core i3 and Core i5 processors, along with NVIDIA GeForce GT 520M graphics with 1GB of video memory. You can also choose from 5,400RPM and 7,200RPM hard drive options and either a six- or eight-cell battery. While the company was at it, it also quietly unveiled another Sandy Bridge laptop, the U41SV, which offers the same configuration options as the U43SD -- and a plainer design. No word on pricing, and a cursory search turned up no availability. For now, though, you can have a gander at some official photos lifted from ASUS' own product pages.
