One of the good things about Nokia phones is they are usually amazingly durable. I've been using Nokia phones for well over 10 years (+ got one tablet) and never broken a single one (Yeah I know it takes luck too). One changeable shell cracked from pressure but that was well, changeable =)

I've dropped my N810 from about 1.5 meters (about 5 feet) to a stone floor without any damage and from about 1 meter (about 3.3 feet) to asphalt and got a scratch on the stand. Luckily still haven't tested the N900 =)
