Ask HN: Will an “as is” software license protect me for now?

I have a software project that I'm ready to start charging some money for.<p>Some people are telling me that I need to incorporate or form an LLC before I start charging any money in order to protect myself from lawsuits. (I would incorporate in the United States.) My thinking was that I'd just license the software "as is" for now, and that would be enough protection until I actually had enough money to incorporate.<p>Who's right?
