Okay, I have to admit that I occasionally get a litle jealous when I read of some people who get copies of books gratis to review. I think, well, heck... I could write reviews. But the plain truth is, I burned out on review writing a long time ago. So it would really be all about getting free books, and I guess there's really no advantage to a publisher to do that.
But today I got an email from a software distributor for major company that deals with publishing tools, and they're sending me the first release of a new suite of tools. Unlike some of the others who send me free licenses that I never use beyond an evaluation, this is a toolset I use and love. (It also comes in really handy if you self-publish.)
I can't complain.
