PowerShell, in my not quite humble opinion, is the best thing Microsoft has done in the past decade, with the second best being Lync. It is mere coincidence that my professional life currently revolves around both.

So, if you are a cheap flight away from Amsterdam, you have until September 10 to join several PowerShell legends like Jeffrey Snover, Don Jones, Richard Siddaway, Tobias Weltner and Steve Murawski, as well as about 60 regular PowerShell enthusiasts like me for three intense days at a price far lower than a regular Microsoft course at some random training center.

The summit starts September 29 (Monday) and goes through October 1, with most people arriving (and hanging out) Sunday evening.
