How these tools are used and % of userbase that cares about them:
- <- Developers
------------------- <- Everyone else
------------------- <- Developers

Do you really think the average office worker cares about examining mount points or finding out how many USER handles a process is using? That's why Microsoft doesn't ship any of that with Windows, and they probably never will. More importantly, I'd rather have a third party write these kinds of tools. They're not limited by what marketing and support think is a good idea to ship. If Microsoft made them they probably wouldn't be as useful - not to mention everyone would whine about how they're evil because they're killing a niche.
As long as these tools are available, I could care less where I have to get them from or what I couldn't do before I install them. Duh.
