I have an OZ in a box in my garage somewhere. It was the second one I have owned. First one's screen broke in my cargo pocket of my bdu's. Crouched down to put the safety pins in an ejection seat and POP! That was it. After that I got a texas insturments Avigo, an Apple Newton Message Pad 2100, casio m-500, palm IIIXe, compaq iPaq 3650, 3850, Sony NX80V, hp iPaq 5550, and now my Zaurus SL-6000. I still think one of the best ones was the Newton, but then again, I am an Apple snob...
