I already have a 1TB external hard drive and back up regularly, so I've got that covered
I think if one could get insurance it would be quite expensive, judging by how expensive mobile phone insurance is.
I was thinking of an imac, which I could bolt to the wall, but would I be allowed to do that in a university room?

My thinking with a laptop was that it could be put away in a cupboard when I'm not in.
Having said that, it would be pretty difficult to sneak out a 27 inch imac from a secure campus....

I was just wondering if anyone needed theirs when out and about that much, especially with things like smartphones and ipads now.
