>Au contraire: It's the height of good programming to attempt to predict and handle as many real-world errors as humanly possible. If I'm writing a USB device driver, you'd best believe I should try to do something sane if the cable comes unplugged, rather than just saying "don't do that".

Should you devote a lot of your limited programming time to catching an exception that users naturally experience during USB operation and can be corrected by a simple "unplug and replug?"

I argue that you shouldn't devote undue attention to something that users naturally already handle.

But if your project is healthy and features are rolling out and you have the time and talent to waste on edge cases like this, then why not!
