Point 4: Insist on Retina... I think there's a better way to do this than you suggest (time-limit before they're kicked for no retina support).<p>Start enforcing this rule after, say, 3 months - to give devs enough time to comply. From then on, any app which is either submitted (for the first time), or updated, needs to have Retina support, or it gets rejected.<p>This stops apps unexpectedly disappearing, e.g. if someone has other commitments than iOS development, whilst ensuring that all well-updated, still-supported apps start to support Retina.<p>I wouldn't be surprised if Apple did enforce something like this if (when) the iPad 3 gets Retina support.
