Reawwy? Hmm, I haven't noticed any degradation of discs stored in my Case Logic et al wallets/binders, and they have been in storage for at least 3 years, maybe more. That said, do I think such wallets/binders are optimal for CD storage? No, but then again, I don't think there is an optimal storage medium. Discs will develop scratches over time, it's called regular wear and tear, and it happens with most anything.
My question to you is, if there is substantial proof that Case Logic et al wallets/binders ruin discs over time, then why are they still a very popular storage choice? If a major design flaw was discovered in their products that ruined discs, then I would imagine Case Logic et al would be out of business right quick. Although, I still see Case Logic et al making more wallets/binders, and people keep buying them.
No, I like women.
