I don't have the time for mobile gaming, so I generally don't buy mobile devices.
So that would be a "no". - Plus with the Playstation 5 looming, Playstation 4 titles will fall by the wayside anyway, making a Playstation 4 Portable a rather superfluous release anyway. - A Playstation 5 Portable however makes things interesting? Especially if it retains support for all Playstation 4 titles.
