That's the reason why I wanted a laptop with a cellular modem inside the case (these are getting harder to find by the way, no idea why). I don't want anything sticking out of the machine while I'm on the move and may have to use it. 99% of the time it is on my desk and plugged in but as soon as I start moving around with it I want it to be free from protrusions because it is only a matter of time before I bump it into something and that will most likely shear the connector straight of the motherboard. So I don't think you're too rough, laptops in transit are simply fragile.
