Really like this approach but 7KG cabin baggage limits on lots of international flights are what makes it really hard for me. I sometimes struggle to get single laptop + iPad + charger + power bank within the limit, let alone two sets.
I always carry two laptops (personal + work) on all trips, domestic or international. Other than added inconvenience of having to take out and put back stuff during security checks, it has always worked out. Even when I end up exceeding the 7 kg limit, I've never been stopped.
