Query: Hinges break easily

I had my unit for a year and the plastic hinge broke.I recommend getting and using the optional leather carrying case at all times because it helps protect the hinge somewhat. My hinge broke after a day I was carrying around my gps unit but didn't have my leather case with me.However I think the hinge started getting more loose after about 9 months of use because the flip cover started falling off my pda occaisionaly after about 9 months of use.Even when using the leather case you'll still want to use the flip cover. The leather case is softer and if you don't have the flip cover on inside the case there a good chace your unit's on button will get pressed on inside your pocket and the pda battery will get drained. The flip case is more rigid and it helps prevent the on button from accidently getting turned on while you are carring the pda inside the leather case.
