Although the small "cigarette pack" cases were ok, I do like the design concept of the current mega pcc case. I personally don't want to carry around a case that looks like a pack of cigarettes. I do like the harder, molded plastic of some, though. However, my only real wants for the pcc would be to have both "trays" be charging trays and add some more carts somehow. I did not like the old mega pcc, even though it carried a few more carts, the new one is much better, more reliable. The storing of the energy is the problem, though I think one day the technology will be there to allow for multiple charging trays and more carts and supplies with some kind of miniature power storage that is not nuclear based or
threatened by airport scanners.
