This is in the same class as the EeePC, but i fear it will turn out to be more pricey than the EeePC 901 Atom model (just as it happened with HP 2133 - its $500 is quite underpowered).

I looked now on some MSI price info and turns out that the $400 version will be with 512MB RAM, which isn't that bad, but i better wait for 901 to come out to compare them.
