Time Machine?

And how do you get to time machine without an OS on the drive or an install DVD?
Likely they'll build something into the guts of Time Machine at some point soon to address this. Always wondered why TM didn't have the provision to set up an "emergency boot drive" kind of thing; maybe it now will. Maybe, too, this is part of the next iteration of Macs; a basic startup system will be "hardwired" into the brains of the machine (non-volatile RAM?) that allows for simple booting and setup.
