Coming from Eindhoven I'am a bit jealous of the Startup community in Amsterdam. But still I would not really consider working in Amsterdam. The 1:20 hour single trip commute by train would take the best of me.

People don't live in SF and work in San Jose much, either.
That said, my underbelly feeling is that Eindhoven is getting a nice startup scene, slowly swelling, though mostly focused on devices and not so much on software. But in all honesty I don't think there's much of a difference. Whether my startup buddies make html5 apps or the next revolution in fitness machinery, we face much of the same kinds of problems.
I think that a startup that grows a fair bit past ramen profitability has a lot to offer to these kinds of people. The biggest problem is how to get the word out.
