Some improvements you should consider:

• Sync iPods, iPhones and iPads over WiFi. Cables are so twentieth century. Palm had bluetooth sync working ten years ago, and 802.11n has the same real-world speed as USB. You could then simply extend this to sync the device to the cloud instead of a specific computer.
• Ditching DVDs to offer an OS reinstall USB flash drive on the new MacBook Airs and Pros is a good idea, but the stick is easy to misplace. How about soldering a read-only USB drive directly onto the motherboard so it can never be lost?
• When someone enters an address in a Calendar entry on iOS, make it clickable and linked to the Maps app, the way addresses in Contacts are. Copying and pasting them manually is a drag.
• Stop adding useless frills like “stationery” to Mail.app, and make the default chronological sort order switchable to “most recent on top”.
• Add HDMI CEC support to the AppleTV. It would be nice to have a HDTV automatically switch over to the AppleTV’s HDMI input when you try to access it. Speaking of which, it would be nice to have an option to disable the audio out on HDMI, e.g. if you have a decent surround sound system connected to it over Toslink and don’t want the TV’s tinny speakers to kick in.
