On the contrary, that's the more common case. It's the case with any computer at work (unless you're IT dept), in any work - there's hardly a job now that doesn't have one interacting with computers in some form or fashion, and those computers are very much not employee-owned. Same is the case in school setting, and so on. About the only time you can expect to own a computer is when you bought it yourself, with your own cash. The problem is, even when you do, everything is set up these days to deny you your ownership rights.
