It depends on how attached we are psychologically to our own personal device(s), but traveling is more pleasant when not weighed down by techno baggage.

The same could go for a phone. If a company specializes in this type of hardware renting service, they could also supply the high speed WAN connectivity and network required to work remotely in this fashion.
