iPod skins

I'm looking into getting a skin for my ipod, and have looked at reviews and narrowed my choices down, but was hoping for some insight. I often have my dock connector plugged in, rarely have it belt clipped(usually in my pocket or my hand or car) and want something that is unobtrusive and keeps the form factor small.

I think i've narrowed it down to the iskin exo2, the lajo exo2, or the new power support silicone jacket. Any thoughts?

 

yeah, i looked at it, but I was looking for something with a little bit of shock/drop protection.

Also, are the reviews about dust/debris collection on the rubber/silicone cases as bad as they sound? Will a wet cloth wipe it off easy or do i have to remove the ipod and wash it?
