Definitely seems cool, but jesus, what happens when the cloud infrastructure breaks? Yesterday’s Amazon Web Services Outage should give many developers pause to relying solely and exclusively to the cloud as a magic bullet (if nothing else, it should be an example of the inherent flaws in single zone deployment!). In this scenario, when the cloud breaks – you can’t even develop locally! YIKES!! That’s a big trade off.
Plus, if i’m not mistaken, with eclipse there are plenty of ways to affect a develop-once-deploy-many facility by way of plugins.
My big problem with IDE’s in general is their interface – it really offers a very clunky out of date workflow. Updating the interface therefore would improve the mobile development lifecycle while not being so brittle by encumbering development with the cloud-scape.
