Its 11pm and I was just off to sleep when I decided to take a quick peek at http://msdn.microsoft.com - and there it is - Beta 2! Excellent stuff. This is a major step for many of the UK ISVs we are engaged with. Check it out http://msdn.microsoft.com/windowsvista/downloads/products/getthebeta/ 

NB: Vista Beta 2 is available only to MSDN Subscribers at this point - but will be publicly available very soon....
