Amazon just started to take orders for the MSI Wind.

The MSI Wind available for purchase is the black model. A very vague shipping date of 3-5 weeks is given at the moment. The price is $499.99 and this is also just the 3 cell battery MSI Wind.

As reported MSI offers the 3 Cell battery MSI Wind for the reduced price of $479.99 on their online shop. The MSI shop is listing a white and a black MSI Wind with a shipping date of July 7th, but ordering is still disabled as the netbooks are marked as unavailable.

Amazon lists also a pink MSI Wind and models with just 512MB. These netbooks are still not available.
