Online retailer Amazon.com has begun to accept pre-orders for Windows Vista, which it says "will be released on January 30, 2007." The company is charging $399 USD for the Ultimate Edition of Vista, $239 USD for Home Premium and $199 USD for Home Basic. Vista Business is priced at $299 USD.
While Amazon frequently lists products before they become available and shipping dates are often an estimate, the pricing usually does not change. Microsoft also appears to be planning a new "Additional License" pack to go along with Vista, which includes just a Product Key and enables customers to use Vista on a second computer. On Amazon, however, pricing for the license pack is only $10 to $20 less than the full retail Vista packages.
