Apple has started shipping its Time Capsule wireless storage appliance in the UK, with the 500GB model now available for £199 and the 1TB version costing £329. The product is available from Apple's UK online store.

When CEO Steve Jobs introduced Time Capsule on January 15 at Macworld Expo, he said the appliance would ship in February; the company met Jobs' deadline with just a day to spare.

Time Capsule is essentially an AirPort Extreme wireless base station that contains a hard disk drive and works with Leopard's Time Machine backup application. With the software and new hardware, users can back up and restore data over a wireless network. Apple has pitched Time Capsule to laptop users in particular, who have had to jack into a cabled external hard drive for Time Machine backups.
