I work for a company that sells all kinds of Mac (and Windoze) peripheral devices (I won't shamelessly plug them here). As a part of my job, I work with a lot of manufacturers. Most of them seem to feel that as Apple keeps changing (without notifying them ahead of time) it's best to make all their peripherals in the Ice/Snow color so any device would match any incarnation of the iMac/iBook/G3/G4. The later version of the Imation SuperDisk Drive is a prime example.
