Brian McBride, Amazon UK MD says
The launch of Windows 7 has superseded everyone’s expectations, storming ahead of Harry Potter and the Deathly Hallows as the biggest grossing pre-order product of all-time at Amazon.co.uk, and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
The other fact is, Windows 7’s first 8 hours of pre-order sales is more than the Windows Vista’s entire pre-order sales. This shows that most of the PC users are all set to upgrade their Windows XPs and Windows Vista to Windows 7.
