I received one of each color on Friday, and they look great!
Both fired right up and-amazingly-have working batteries. I haven't tested the battery life yet, but it's at least enough that the computer will completely charge and will stay asleep if unplugged. Anything is a big improvement for me over my other Clamshells. I have a mix of factory and aftermarket batteries, and all are dead as a doornail.
In any case, I did have to do a bit of OS 9 magic to defeat the password on the tangerine, and ended up reinstalling OS 9 so that I could get the "official" OS 9 Tangerine desktop back.
I couldn't be happier, though. The ones I received have writing on the bottom rather than the top. I'm a chemist, and am going to take my time trying to get it off.
Thanks again!
