Sounds like hours of pondering about international tax issues would follow this decision? I have a sole proprietorship in Finland. Sometimes I've given thought to having this type of standard corp in US, as if I have another hit Facebook app or whatever it seems like it would make me an easier entity for others to deal with. Apart from the tax issues, I worry about having to pay an US lawyer high US wages for advice / set up fees. Maybe I'm starting to believe all the news stories too much, but doesn't being incorporated in US also make you much more likely to be the target of some frivolous patent / other lawsuit?
