Let's say this ends up being 30$/month (I've no idea how much it will cost, but I saw this number floated above).
Let's say you replace employee machines every 2 years.
Doesn't it make more sense to just spend 720$ extra per employee on hardware? It'll be a much better experience, with much less risk (what if mighty is unsustainable and closes down?), and that machine will still have value in 2 years, unlike throwing money at a cloud subscription.
Fwiw, I still feel the pain on a top of the line 16" MBP. For many tech workers, a laptop is what they get, and what they rely on in terms of portability vs performance trade off. Using this is probably more convenient than getting beefier hardware, which I suspect is gonna have to be a bulky souped up workstation.
Imagine all the enterprise customers who'd be willing to pay for this so their designers and engineers can be more productive.
