UPDATE: about the battery!
I've already reported that Medion is going to bring to the market an ultra portable laptop built on MSI Wind basis.
My personal opinion is that MSI Wind is most promising/best ultra portable laptop announced so far: the best feature-set + very good price level.
Some more details about the Medion Akoya Mini E1210: it will be sold/available starting from July 3rd in Germany (Deutschland) for 399 Euros with Windows XP Home, 10-inch display, 80GB hard disk and a 3-cell battery!
To be noted that the Medion Akoya won't include Bluetooth!
