That is indeed one of their premise. However that also has, perhaps unforeseen, implications. To start with, their VMs have to be at least one step better than the end consumer's machine. Can they do it without increasing their price? Secondly, there's no guarantee that developers will overwhelm even Mighty's cloud resources?

All that said, it's worth noting that the first set of customers seem super impressed. So maybe Mighty are on to something.
