the proporta case:
http://www.proporta.com/detail.asp?id=406&Curr=USD
I have two little girls who like to dig through my purse, and rearrange things. With an aluminum case I figure they won't be able to harm the axim.
And I just keep cards in the ax, and don't carry around extras, but if I did need extras I think I would keep them int small pocket of mypurse in the plastic carriers that they come in, or on a trip they would be in my camera bag anyway. . .
I had the dell leather case, and it was bulky, didn't fit right, seem to let the ax slide around quite a bit, and shed black specks!
Guess you can't win 'em all, I am sending the leather back. I think the sena case is a great option as well, but with two little ones, I figured the least exposure as possible was better!
