Windows 7 Leaked To eBay but buyer beware article at Informationweek.com http://ping.fm/xrvRF
Sellers are using the online auction house to hawk Microsoft's new operating system weeks before official release—but buyer beware.

Some sellers are pitching retail boxed versions of the software while others, the majority, are offering registration keys that allow users to activate a previously downloaded copy of Windows 7. Microsoft has already released Windows 7 to businesses, so it's possible the sellers obtained access to the software keys through their jobs or other professional contacts.

It's buyer beware, however. The software may lack Microsoft's official Certificate Of Authenticity and other piracy protection measures. So it's questionable whether purchasers will receive support for the product, or whether it will even run at all.
