If like me you where unable to watch the keynote from yesterdays BUILD conference (I was on baby pickup duty) then you can watch the recording now at http://www.buildwindows.com/
Go download the Windows Developer Preview and developer tools to start building apps now! and read the press release about Windows 8 and what we shared with developers, access official Windows 8 screenshots and more.
Plus watch more technical sessions over at channel 9 from the Windows Engineering Team
No Powershell tag for Channel 9? With PS becoming such an integral part of Microsoft's future, that seems like an oversight.
