Many iphone/ipod accessories are cheap now, discounts and time have all lowered the price. I'm thinking of stocking up cases and screenshields so when the new version comes around, I can alternate and customize the exterior to many different colors and different designs. Of course I am also risking the fact that there could be a new redesign in iphone5/ipod touch 5g which would completely neutralize my plan. iPhone5 rumors has it that there will be same form factor as the 4 and weren't 3g and 3gs cases interchangeable. iPod touch 5g may be even thinner but I think it has reached its limit and weren't 2g and 3g touch cases also interchangeable. What do you guys make of my decision? Useless? Risky? Dumb? Interesting? Peculiar? I haven't bought any cases so I can still not purchase them.
