Like most slashdotters, I'm in IT.
The last couple of companies I've worked in, have made the decision to allow us -employees- to admin. our PCs.
We are mostly semi-senior developers: we have the knowledge to make our computers perform their best, and we know what we want -and need- from them. No one else -not even support dept.- can know what service, application or tool is best for us and, being highly trained, we're the best admins. these computers could have.
-- For instance, even though we need to use Windows XP, no one uses IE --
And last (but definetely not least), this is what we *do*. Most of us could hack through the security policies if they were there. I don't think that having over a hundreed skilled developers trying to bring down your security infrastructure is the best way to go.
Whenever I start my own company (that's right, I still like to daydream), I'll make sure I hire talented, trustworthy people, and grant them admin. rights of their PCs.
PS: Note that admin. of PCs != network admin. Everyone here should appreciate the difference
