The effort companies seem to be spending on bridging the gap between mobile and desktop just doesn’t seem to be worth it anymore.
I remember when I got the first iPhone: it was an extension of the Mac, allowing you to reach your desktop data when away from your machine. These days I barely boot up my Mac unless I have to bang out a CV, properly edit a video or use Photoshop.
For pretty much every other computing task, from managing your finances to playing Fortnite, a phone (or tablet) is just more convenient. Using the mobile space to reboot the desktop market is a fallacy because away from work, how many of us actually sit down at a desk and use a computer anymore?
The work situation is perhaps slightly different. The dream of plugging your device into a workstation and using it as your PC sounds great on paper, but it would be a security nightmare for the IT department given the menagerie of devices we all have. A closed system of company-owned machines is much easier to lock down.
