Guys,

I'm after a bit of advice for those with experience of external hard drives. My girlfriend is getting on for her MacBook Air as the thing only comes with 80GB on there. And I will also use it for me PC. She is looking to get the Time Machine from Apple, either 1 or 2TB, we're undecided.

What I want to know is whether it's worth it for the price, or if we should just go for something cheaper, off the shelf from a PC specialist, and would this work okay with her Mac?

Looking to spend about £300/$500 on one.

Thanks Guys.
