Even if I owned one of every generation of iPod and iPhone I don’t think I could fill the Parasync, a nifty charging and syncing dock that can handle up to 20 devices at once.
The only real downside is that it seems you have to sync all the devices to the same iTunes account, though you can probably put different libraries on each device, and of course iPhones and iPod touches will handle apps as well.
I wonder what the record for the number of Apple portable media players owned and actively used by one person is, and whether they’d stump up the $980 to own one?
