How is a laptop a substitute for a work phone? The whole reason for work phones is that people carry them everywhere. I am confused by this entire concept, I guess. I mean, I understand what it does; I simply don't understand why.
You don't need to carry a work phone anymore because you can access it on your personal phone, in a browser. Think BYOD, but without mixing the personal data with the business one. And when you're at work, you can access it on your (work) laptop, again by simply opening a browser.
