It's a pity that clear cases always get lots of dust and fluff between them and the phone.
True, to an extent, but I love clear cases. I want to be able to see the colour and design of my phone. If it's a well fitted case and you make sure that it, and the phone, are clean when you put it on it shouldn't collect that much junk, and all it takes is an occasional removal and wiping down to keep it clean.
