Amazon UK: Windows 7 is 'the biggest pre-order product of all time'

From TG Daily -

Amazon UK has announced that the new Windows 7 has sold more copies in the first eight hours of its release in July than Vista did in its entire pre-order period. The new OS launches officially tomorrow (October 22).

The launch of Windows 7 has stormed ahead of Harry Potter and the Deathly Hallows as the biggest grossing pre-order product of all-time at Amazon.co.uk, and demand is still going strong. Over the past three months, only Dan Brown's The Lost Symbol has sold more copies than Windows 7.
