I know about it, but licensing for 50 servers running IIS on Windows 2008 vs 50 servers running LAMP is a big price difference to even a medium-sized company, let alone a startup. I also wouldn't bet my company's success on whether mono is working correctly this version. Oh and if you start building on that infrastructure using AD, Exchange, etc you're in CAL licensing hell. Next thing you know you've spend the wages of two really good engineers on just MS licensing. How is that cost efficient? I'd rather have a 5 man team running linux than a 3 man team running MS. Not to mention, if I'm recruiting young talent, how many of them will have MS enterprise experience vs linux-based experience?
