Microsoft have announced the first month's sales figures for Windows 8. 40 million - Windows 7 sold 60 million in the first 10 weeks. And, to put those figues into perspective, the total sales of its only commercial competitor on the desktop, OS X, are 66 million. So in another month or so we can expect there to be more Windows 8 users than OS X ones.
Not bad for an OS that some are writing off as a failure.
