>> A backpacker will be backpacking in the country for 10 days. Rather than having the hassle/cost bringing over a tent/sleeping bag they would like to rent them

Maybe some but I suspect many climbers/hikers put a great deal of faith in their equipment. Rental equipment is often abused. Beyond that, they aren't comfortable with it which adds an element of risk.

>> A business person visiting Dublin for three nights. This person would like an ipad for this time.

A business person traveling internationally will have all the tech they need and then some.

Good points. I think you are correct with the business user: also vpn/security would likely mean that it would be unusable for their needs.

Perhaps people would like to rent the latest tech products and use them while on holiday. They would get to try out the latest Ipad/nexus in the real road.
