So, I really like VMware's products. I don't "just use them" daily as part of my work. I like working with them so much that I made an effort to become good at it so I could work on it all day :)
I get excited with the technology. I use it as part of my workspace, I play with it in my home labs, I read the books and news, and other's blog posts, with extreme interest. I involve myself with the vCommunity as much as I can. Being a VMware administrator has been one of the coolest experiences in my professional life!
Good VMware links to have handy
