Most portable VMSs have a cell phone in them, at least in or around NYC.

Without people like Tesla, there would be no progress. We stand tall because we stand on the shoulders of giants. Any other attitude would be like putting down Thomas Edison for not coming up with LEDs.
Nice statement except that I do not like Edison for electrocuting an elephant trying to show his inferior electrical system was safer than Tesla's AC system. Unforgiveable.

Oh, I realize it when I see flip disks.
They are often fluorescent green. Sometimes with a black light which causes them to fluoresce.
Also very pleasing sound when operating.

Thanks,
