Hello, I posted with much the same thoughts Mary, but for whatever it's worth, I find it necessary to say that I agree with you. I just hope that those of us who choose not to, will still be able to use the old units if another revision comes out. On this one, I will go with my professor who used to say that newer, is not necessarily better.

The bp isn't all that thick now. Flexibility beats a reduction in thickness imho. Smaller isn't necessarily better; and what happens when the built in proprietary battery dies? Send it back for a costly fix? No thanks. The nice thing about these units as they are now is that its really easy to swap batteries, and we already have the ability to use nimh if we so choose.
