Query: Took it all over the world, and it still works

I have read a lot of negative reviews on this system and would just like to add my own Imput. I bought my NJ3 in SEP 02. I took it with me to Afghanistan for 7 months. Afghanistan happens to be the worse place for Electronics in the worlds. Dust and filth... Just Awful. I dropped my player quite a few times. Took it with me on missions. Used it every single day. After 2 years my player still works perfectly. Its worn beyond belief but still works fine. Just letting all of you know these units are as tough as them make them....
