I believe that while LinkedIn is useful and having it won't hurt in any ways, having resume is also necessary.

I cannot say a receive lots of work requests, but the usual pattern for me is that HR people find me on LinkedIn somehow, contact directly and ask for a resume.

I've been in the same situation. What I dislike about this is that my resume doesn't have much more information than what I've chosen to feature in my LinkedIn profile. I suspect that this is all about formalities, and that their recruiting and/or HR policies require a resume.
