I'm looking to buy a case for my ipod. I'd prefer something small/not bulky, clear perhaps... I think the DLO Jamjacket and the iskin exo2 might fit the bill? I dunno, I was checking out some stuff online and it's hard to tell if something is decent or not. Being able to plug into the dock while wearing the case would be nice, but isn't a necessity. However, being able to hook up the cable while the case is on is a MUST. I'd also like for the screen to be protected (I'm not sure if that's standard on all cases or not). Oh yeah, I'm also rocking the 40gb unit. Anyone have any recommendations or warnings about which cases may or may not work? Thanks.
