S-Corp/C-Corp/LLC
mdasen: This isn't going to be the answer that you want, but it doesn't matter what corporate form you take.  What matters is what you build.  LLCs are going to be the least work.  You won't sacrifice things down the road - worst case, you and your partners create a new Corp and sell the LLC to that corp.Most likely, you aren't going to attract VC investment (most companies don't).  LLCs can grow very large (like Fidelity Investments which has profits of $1B per year).  They require little anything to run them.Just make your product.  If you're successful, it won't matter.  If you're unsuccessful, it won't matter.  This is just distracting you from making your product.
