A very expensive way to back up data, but nice to look at, efficient, and makes a decent wireless router as well. It took me a while to get it to work, I had problems with a file that `time machine' did not like. If that happens to you, download Time Machine Buddy from Apple. It tells you exactly what file it is and you can exclude it from the back-ups or delete it. I would recommend shopping around though before shelling out £200 for a Time machine. It is only back-up you want.. not a fashion statement.
