The success of the PRODUCT (RED) AIDS fundraising program has started to spawn imitators -- the Alzheimer's Association has picked purple as its "signature color" and SanDisk is first out the gate with a co-branded USB flash drive and SD card. The purple 2GB SanDisk Ultra II SD card and 2GB Cruzer Micro drive will retail for the same price as their non-disease-fighting counterparts, but SanDisk will donate $1 per unit to the Alzheimer's Association, up to a maximum of $1M. We're happy to see a good concept extended, but unlike the flashy (RED) devices, no one's ever going to see you flaunt that purple SD card while it's in your camera -- what will the fashionistas ever do?
