Also, I’d love to see a lot more integration between devices that didn’t involve iCloud. Device awareness — especially proximity awareness (e.g. the movie Avatar’s ability) — would be a great differentiator.
Also, what happened to the plans to make FaceTime an open industry standard? Apple needs to rely on all computers — Windows included — to support the software in order for it to really become the revolutionary offering Apple has made it out to be.
The tech that FaceTime is built on is a collection of open source and licensed tech that Apple does a great job of tying together. All Apple really has to do is to release their code and any licensing dependancies and let the third parties work out any licensing issues — if they have any.
