Im not sure on seo as I've never owned a info domain. But as a customer I don't trust websites with info extensions, don't know why, perhaps because they are not as well known as the org's and com's. Just personal preference I guess
i dont think there is any impact on SEO for .info domain instead of .com domain. all depends on the quality content and the marketing strategy you use to promote it.
As I think most people usually keep in mind the domain name not the extension then they usually try with .com then if its wrong they type .info, .org etc. If you own .com its much easier to become successful sooner than having .info
