At the 2006 WWDC in San Fransisco, Apple CEO Steve Jobs announced several new products during his opening keynote speech. Read more for a chronological summary of the keynote-- including the much-debated preview of Mac OS 10.5, Leopard, which, according to Steve Jobs, will ship this spring. Update: Apparantly, a similar feature to Time Machine already exists in Linux. It is called 'Dervish'.

Actually, Time Machine is nothing at all like System Restore.
...
Time Machine backs up every file, every time it changes, and is intended not so much to restore the system when you install Super Online Game and Spyware Program, but to restore your files when you accidencally delete them.
You're correct that this isn't like System Restore, but it is like volume shadow copy (Server 2003 and Vista) and CompletePC Backup (Vista).

FreeBSD has filesystem snapshots as well (since at least late 2002).
mount -uo snapshot /var/.snap/0 /var
I have a cron job that rotates snapshots for monthly, weekly, daily and hourly backups. You can mount the snapshots like any other filesystem image.

Not quite. From the time machine page:
http://www.apple.com/macosx/leopard/timemachine.html
Backup Time: Time Machine will back up every night at midnight, unless you select a different time from this menu.
So Time Machine is a standard sparse backup utility, with a very slick layered GUI. It doesn't back up files continuously, which would require a COW filesystem to be anywhere near feasible. Applications must use new APIs in order to access these alternate versions. Very nice GUI and integration work (which Apple is always good at), but the underlying filesystem technology is rather mundane.

Actually, Time machine is very similar to the way System Restore works on Vista, as MS have added file versioning on the filesystem level:

Actually, Time Machine is nothing at all like System Restore. System Restore backs up the registry and certain Windows files (.exes and .dlls that are crucial to the system) and filesystem status at pseudo-random intervals. When you want to restore from System Restore, you need to restore the whole thing, which usually deletes most of the files created since the restore date, and screws up any programs you've installed since. Time Machine backs up every file, every time it changes, and is intended not so much to restore the system when you install Super Online Game and Spyware Program, but to restore your files when you accidencally delete them.
The new Dashboard feature is probably a little bit like Active Desktop, except not really. I won't comment too much.
Finally, as to Virtual Desktops, they've been supported on *nix window managers for a long, long, long time. Of course, they were not a stock feature on Windows 95, so I'm not sure exactly what you're talking about. OS X has also had better support for multiple screens than Windows has for a long time, with the playing field becoming level only with the release of Windows XP.
BTW, yes, I know you're a troll. Oh well.
