I know some of the tools are totally useless but some are really usefull like the process monitoring ones.
even though, afaik, they use WMI, so doing your own shouldn't be a problem. (iirc, we have one written in kix already)

what I really don't see as a good thing is the integration to MS site.
those tools will get buried in the mass of trashy documentation and marketing pages.
well, as long as I know they are there, I might be able to find them in the years to come.
