Hi, I'm a Switcher in the making - can't wait for a 15" AluBook ... For the moment, though, I'm battling on with my crash-prone Dell Inspiron 8200. Because this machine is so unstable I need to get hold of an external back-up solution (I have reformatted and clean installed countless times now). However, with a move to a Mac pending, it would be silly to spend on a solution I wouldn't be able to use with a Mac. So, my question to you all is: Can you suggest a cost-effective, relatively hassle-free, external back-up solution which will work with both PCs and Macs? All responses greatly appreciated, benjiP.
