Is that a joke?
Windows 7 did that in preorders in the UK alone, before the product was even launched, not to mention the US and other countries. It even oustold Harry Potter.
“Amazon: Windows 7 is ‘the biggest pre-order product of all time’
Windows 7 has beaten boy wizard Harry Potter to become the biggest pre-order product of all time in the UK, says Amazon.
The UK arm of the retail behemoth adds that the new operating system 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“The launch of Windows 7 has superseded everyone’s expectations, storming ahead of Harry Potter and the Deathly Hallows as the biggest grossing pre-order product of all-time at Amazon.co.uk, and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,” says Brian McBride, Amazon UK MD.”
