The Toshiba T135 CULV Windows 7 Notebook starts at $599 on Amazon.com.
Hothardware has tested the Toshiba T135 and published this review.

Quote from the review: "We're seeing more and more CULV notebooks hit the market these days. The growing sector of Consumer Ultra Low Voltage machines attempts to bridge the gap between lower cost netbooks and full-size notebooks, offering a more powerful chip than the ubiquitous Atom options we see in netbooks, but one that consumes less power than the mainstream Core 2 Duo processors we see in many full-size notebooks.
The Toshiba Satellite T100 Series fits in the CULV segment and attempts to offer the comfort and convenience of a standard laptop in an ultra-thin package. As the larger model in the T100 series, the T135 we look at this in article features Windows 7, a 13.3-inch widescreen display and measures only 1.35 inches at its thickest point."
