They are now available MSI Wind U100-420US for $349.99. They are being listed as available in 1-2 weeks (that may change depending on supply / demand).

There appears to be an error with the graphics chipset listed on the Best Buy site – BB is listing it as “Intel Graphics Media Accelerator X3100 graphics” but I believe it’s the standard Intel GMA 950 that is available with other U100 models.
Whether there are any other models or colors probably depends upon how well these do.
Thanks to Tim for emailing this.
