It happens far more common then most people think. I worked at a company where the Accountant was paying bills as they come in. It was only after she left and her replacement questioned it did we realize that we'd been paying a company like that for years.

I've been using my own devices for work since 2005. When I worked in a motorcycle shop the mechanics brought in their own tools. So why now that I'm a programmer should it be odd that I bring in my own PC and tablet? What I would like to see companies do allocate a specified amount each year toward equipment.

As for security, Novell just released a Dropbox like application with enterprise security in mind. It's called Filr.
