reed switch?!? that's a bit old hat; one would hope that any recent devices employ hall effect technology
Reed switches are cheap, robust (mechanically and electromagnetically), accurate, and simple to interface to the electronics (no amplifiers, "signal conditioning" is a simple debouncer). If it's not broken, don't fix it.
