Apple's just slipped something into its iMac update press release that we didn't want to go unnoticed: a battery charger. Apple's AA battery-powered lineup now includes the Wireless keyboard, the Magic Mouse (which seriously burns through the juice) and now the Magic Trackpad -- now have a charger to call their own, and for $29 you can grab one up. The Apple Battery Charger comes with six long-lived rechargeable batteries which apparently have a lifetime of up to 10 years.
