Great way to end a pain in the ass day. As I am packing for my trip back to the beach I recall the new TSA restrictions on batteries.
I usually travel with my Canon 1D Mark II N, though you'd be hard pressed to tell that from my flickr feed. :S
The bad news is I had to decipher this confusing post of allowable types and quantities of lithium in batteries.
What it appears to boil down to is that the average modern laptop and cell phone are below the allowed 8grams. So, as long as you've only got two devices and they're both modern, tada! You're probably OK. But, as I've seen with the 1D security check points are arbitrarily different in what they will run through twice or pull me aside to more thoroughly check my equipment.
The 1D and all modern Canon cameras use Nickel Metal Hydride (NI-MH) batteries which are not restricted in any way.
The point is I had to spend 30 minutes investigating whether I can 'safely' take my same three items that I usually travel with (Canon 1D Mark II N, Apple iPhone, and MacBook Pro) on my my trip home to Jax.
Special thanks to the Boing boing comments for both the laughs and helpful links on the subject of the new TSA Restrictions.
 Don't get me started (too late) on my on-going ordeal with Apple Support (Day 10) trying to get my MBP 'fixed'. I am posting this from said machine with the ominous warning to not turn it off "It doesn't want to boot reliably and we don't know why." Thanks to Brian and Dan at Apple Store Madison West though for the helpful support today. Now I get to turn it over to the Geniuses at Jacksonville's St. John's Center for further repair.
