I've noticed the trend toward AAA's too. Most remote controls are now AAA, and of course the famous ARC flashlight is AAA, as well as my mini-radio, Aurora headlight and Maglite. I stock more AAA's these days than AA's and I keep around a few AAA to AA converters for that reason - In many cases AAA's can substitute for AA's, but the reverse is not true.

I refuse to buy anything with N or AAAA cells since finding those battery in an emergency could be difficult
