Whoops! Sorry about the lack of replies to this post. I missed the comment until it was pointed out by Beth Blakely one of our great Community Editors.
Anyway - about TechRepublic Pro. There are over 300 exclusive downloads that are included in a TechRepublic Pro membership. These downloads consist of several different things, including ready to use forms, spreadsheets, policies, procedures, checklists, and so forth. The main idea is that TechRepublic Pro downloads are designed to take some of the tedium out of IT work and to help you get your job done more efficiently.
There are also ebooks that cover lots of different topics than Microsoft stuff, as one poster here incorrectly mentioned. There are administrator guides for networking, wireless, Macs, and Linux. It's hardly 99% Windows.
If you click the Store link, almost all of those downloads available in the Store on a Pay Per View basis are available as a TRPro member along with 200 additional downloads, some of which are electronic versions of Books and CDs that we used to sell. If you bought the downloads out of the Store that are available as part of a TRPro subscription, it would cost you over $3500, so the $129 rate is a pretty good deal. We add new downloads to the library at a steady rate, so that value only gets better.
To see all of the downloads that are available for free as a part of a TRPro subscription, follow this url:
