I drop my N900 onto a hardwood floor two times couples of weeks.ago.. and it survived..... and then I drop my N900 again over the weekend onto the concrete floor from table level *no scratches" Wow!. only the slideout keyboard was slide out and the screen lid. Phew!!! again survived.

... and then when i climb into my house attic to do some cleanup work..., and lost it there..and later found it back with no scratches too but covered with dust..... amazing.... it survived.
