'Pebble' got $10M for a bluetooth enabled watch.. hardly unique, but lucky and well marketed. The common theme for those that raise decent amounts of capital are that they're US based, preferably silicon valley. Even those aussies had to relocate...
Take care with the survivorship bias too when looking at these kickstarter projects. There are 1000s of them.. unless you've got something remarkable that can get techcrunch, Scoble, or other members of the 'internet royalty' club to promote you, its little more than buying a lotto ticket... not something you can plan for.
I'm also a bit anxious about how trade practices interacts with KS... it hasn't been tested in AU courts, or US ones for that matter.What happens when a project spends that money and doesn't deliver or can't deliver.. I personally wouldn't want to be a test case...
