So, Vista users are getting free WI-fi provided by the Cloud until April 30th... but of course, hackers already found out how to take advantage of this. According to an article on The Register:
"US hackers quickly discovered that their equivalent service was only checking the UserAgent to confirm that a customer was using Windows Vista; something which is easily changed with modern web browsers. This loophole is likely to be quickly closed, and the requirement for a Vista registration code would indicate that in the UK the offer will only be available for genuine Vista users."
Anyways, as the article mentions... it would be interesting to see who is paying who for this service.
