Comet are selling theis 1TB USB HDD for just £44.99 while you can get one at amazon for about 42, this means you can walk into a comet store and collect it, ever reserve it online and collect in store 30 mins later. Brilliant. Excellent value for money
Comes pre-formatted as FAT32 so you can use it straight on the box on mac/pc/linux
I'm using it for Time-machine on on an apple Imac. it even puts it its self into standby when its not really in use.
