While I have been generally happy with this cover, I do think it is a bit over-designed. There will be individuals subjecting their iPod Nanos to severe impacts who may realize value from this product. Yet, I actually believe most silicone or leather covers will suffice, no matter how abusive the abuser is. For some, the particular appeal of the ToughSkin design may be cosmetics. In fact, it would pair nicely with ruggedized Nextel phone.
One may ask, what could be the problem with an extra thick cover? The biggest annoyance is its interference with the control surface due to the thickness of the rubber. The circular edge on the main opening is beveled to add clearance, but it is still difficult to control the player, especially when inside of a pocket.
What strikes me a bit odd is the ToughSkin does not hold the Nano in position firmly enough. The player shifts occasionally, which then misaligns the main opening. Clearly this is a design flaw.
Despite its shortcomings, the ToughSkin is a nice protector. The notched rubber will absorb severe shocks. In addition, it has some nice extras. Much like a cell phone holder, it comes with a swivel belt clip. Unlike many Nano covers, there is an integrated screen cover. In the end, considering the pros and cons of this accessory, it is a bit overpriced - much like all iPod accessories.
