I have read through a couple of old External HD threads and got very confused. We have two 80GB MacBooks plus a 60GB iPod to back up, and I imagine I will want an extra 50GB+ for storing extra music that I acquire over the next few years. Therefore 320GB should suffice. Any recommendations? (I live in UK so please consider this if you want to suggest particular deals.) Should I go for USB or FireWire and why? How easy will it be to connect to it wirelessly?
