From past experience (not for quite a few years, but some at least): oh heck no. I loved simulating locally, but the deeply limited touch handling made it infeasible a lot of the time. The dev -> install -> run -> dev cycle is dramatically faster in the emulator, and you don't need to have multiple devices nearby if you're building custom UI for each size.

Macbook Pros attempt to cater to every slim use case simultaneously, with the idea that if they can handle a use case someone else can’t, they’ll sell another laptop.

yea but if the company is footing the bill...
