Measuring in "number of laptops" is frankly an extermely bad way to look at the things.
Look at for example the Lenovo line, if the MacBook line is at confusing, the Lenovo line is impossible, so many lines, people don't know what to buy for them, and to point to friends which model they should buy. And quite frankly, most of them are SKU's you really should avoid. And worse, when you go to a Best Buy or similar to buy one, it never has the one you want. Either is 1080p, and you want HiDPI, or has too low RAM, etc.
For Pro-level software the only thing that went away was Aperture, that nobody used, but a vocal minority, for the vast majority of photographers, they used Lightroom, that was easier to use, had more tools, and more importantly, produces better quality photos.
