What are your questions about it? I know two startups friends did that used it (one I was a part of), and the program is exactly as advertised. All the software+licenses, free for use until you either pass the 3 year (IIRC) mark or several million in revenue. It also now comes with some free Azure time.

If you can stand the HN karma deduction of using the MSFT platform, it's a pretty fantastic deal. Oh, and the program administrators are less picky with how "real" you are than, say, becoming a registered iOS developer (having gone through both processes myself).
