I'm one of those professional media types #19 mentions.

Right now I'm on the road working with 4(!) different types of Lith-Ion batteries and one batch of 12 Lith-Polymer rechargeable 9-volts. All told, I have 26 Lithium-whatever batteries in my kit. None of them are marked with Li content by weight. I can't physically take all of these in carry on, unless they seriously redesign overhead storage.

And, usually, I'm flying with more than this. I can't wait to spread this to the network news folks I know - they'll just love it.

Guess I'm just lucky I get home before New Year's Day.

Fair warning: this locked up my MacBook Pro running OSX 10.4.11. No idea if this was a problem w/ my machine, but it is the the first time that's ever happened. Couldn't escaped, force quit, anything.
