Apple today introduced Time Capsule, a backup appliance that automatically and wirelessly backs up everything on one or more Macs running Leopard. Time Capsule combines an 802.11n base station with a server grade hard disk in one small package. Simply plug it in, then easily set up automatic wireless backup for every Mac in your house to a single Time Capsule with just a few clicks. Time Capsule offers the benefits of a full-featured 802.11n Wi-Fi base station, and comes in two models: a 500 gigabyte model for US$299 and a 1 terabyte model for $499. Time Capsule will be available in February.
