Microsoft had decided to give Windows Vista Beta 2 to public for free and now you have 2 options –
Order a DVD or download about 3.2 GB of file data from Internet. The choice is yours.
MS didnt distributed the package in bit torrent form and hence its website ran through overwhelming traffic for download requests and bcoz of that, MS had to push public to go for DVD option. But Chris Pirillo and Jake Ludington have done this great job of providing bit torrent version without any sanctions from MS.
