Actually having to develop (browser, IDE, compilers, etc) on a slow machine is pointless torture, but I do see the value in the app that you're building running

Actually having to develop (browser, IDE, compilers, etc) on a slow machine is pointless torture, but I do see the value in the app that you're building running in a resource constrained VM or equivalent. That way your dev experience is crisp, but you get a more realistic sense of how your application functions for the end user.
