Hello,
You will see people with Ipad's etc every where and not only tourists. It should not be an issue. You will have more probably that a tourists stole your belongings than a local. Just take care of it.
The same can happen while on the beach and decide to go for a swim... what will you be doing with your cameras etc ? I have never had problems in Panama. There are plenty of WIFI in Panama so it will be useful to have it.
Best regards.
