Between phone, powerbank, headset and cameras I put so much stuff out of the luggage through security[1] that I don't think adding or not a laptop/tablet matters that much.

Also unless you carry 5 meters usb and hdmi cords I don't think that use case is so universal. Power outlets are usually so badly located in hotels.

[1] basically I empty the handbag of everything that is not spare clothes. It is just easier to throw everything on that plastic tray than filtering what needs to be shown or not.
