Maximum PC Reviews the Toshiba Portégé R700
"Toshiba says this represents a new direction that will be mimicked in all of its laptops going forward. For one thing, the R700 isn’t as wafer-thin as the R500/600, although it still sports a very slim profile at just a tad over one inch thick, and weighs a mere three pounds. The chassis is reinforced with an internal honeycomb design and features a magnesium-alloy top with an attractive anodized black finish. Even when held by one corner, the laptop feels sturdy and rigid."
The review is a bit light on details, but overall it looks like a decent machine if you are looking for something in the thin and light category that is suitable for business apps.
