Chris Sells provides a lot of info in this post about resources that you can use *today* to get your job done. Being in the field, this is a subject that is near and dear to my heart. I love the Longhorn story, and there are definitely a lot of really cool technologies in the pipeline that we need to be getting ready for. Rest assured, however, that Microsoft is fully committed to helping you get the most out of the tools that you already have. If you can't find an answer in the list that Chris laid out, just ask, because if there's one thing that I do know about this company, someone knows the answer to your question.
