MSI this afternoon grew its American roster of Wind netbooks by importing the U110 Eco. The new model is the only one based on Intel's newer Z500-series Atom chips and uses a 1.6GHz example that gives it a much longer claimed runtime of up to about 15 hours with its standard nine-cell battery pack. Unlike the version announced earlier in the year, though, the US version uses the GMA 500 graphics inherent to the Z500 line than a much faster dedicated chipset.

Moving past these, the U110 Eco brings familiar specs that involve a 10-inch display, 1GB of RAM, a 160GB hard drive, 802.11n Wi-Fi and a webcam. MSI does give a choice of operating system, however, and says versions can ship with either Windows XP Home or Vista Home Basic.

Officially, the system ships for $430 in its single configuration, though a NewEgg listing already has the same system available for $400.
