True, or... the "phone operating system" has evolved to the point where it can replace the function that the laptop previously performed, for some number of people.
A similar story is playing out with digital cameras. For the average person, the "toy" smartphone camera evolved to the point where it replaced the traditional camera. Ask Canon and Nikon how that's going.
Not quite yet. Photo editing, video editing/rendering, office, etc., etc., while part of that can be done somewhat on ios it's not remotely the same as on osx or windows and has a long way to go. Evolving to osx like and evolving to make hardly difference at all are two different things. Photo editing, office, is kind of a simplistic extention of the osx counterpart. I do photo editing, video editing and have a subscription to office. Not even close in any of those. Anyone that can get by solely on the ios apps as they are even now never needed a laptop. Not saying it won't as it probably will some day, just that as of now the evolution is still closer to what it was several years ago than to laptops.
The camera has nothing at all to do with it and apples to oranges but since you want to bring it up my dslr is a camera, phones still have toy cameras. I think the toy phone camera filled a spot for people where they do not normally have a camera with them. A dslr is for taking pictures for functions, etc. Anyone that takes an iphone to take wedding, baptism, first communion, etc. pictures is not serious. Pic's at the beach? Sure, but MOST people never had cameras with them for stuff like this before phones. There are 5 of us here with phones, iphone and android, and up against my dslr they all look like toy cameras.......which is fine for casual areas where you would not normally have a camera otherwise.
Will they some day take the place of cameras? Maybe but there is still a long way to go.
As for the future the camera companies would be smart to work with phone companies making the cameras and lenses.
