MSI says the Windows XP version of the company’s Wind laptop will be available in the US on June 16th for $499. And while UK retailer Expansys has a web page for the Wind for over a month, the computer is just now starting to show up at US web stores. MWAVE has the MSI Wind laptop listed for $499.99. It won’t be available until June 23rd, and that’s listed as an estimated ship date. But it still beats Expansys, who says the computer will be available on July 22nd.
