Gratuitous summary plus commentary:

- iPhone is only programmable via dynamic HTML. Unspecified: what are the APIs? Can you get at the audio codecs? (Can you write Skype as a web app?)

- Snazzy remote desktop support via .Mac ("just drag a file and it's there... boom"). Unclear the extent to which this works with iTunes. Can you keep playlists in sync across machines, rather than just from computer to an iPod?

- Safari has been ported to Windows. Weird.

- Mail integrates a little better with iCal.

- Apple now has a WebDAV / CalDAV server (iCal Server) as part of Leopard Server, which can schedule people, resources, etc.

- Likewise, Leopard Server has some kind of shared search engine that understands file permissions (i.e., it indexes everything, but only feeds results based on what's readable by the user).

- iChat Server, which can save conversations, videos, etc.

- TimeMachine is certainly cool, but no mention of ZFS, which would make all the difference for me.

- No new hardware announcements. No replacement iMac. No replacement Mac Mini. No new laptops.
