I just had to post about this. My iMac's HDD was dying, so before the warranty was up I took the machine back to the Applestore and told them it was dying. They took the machine and replaced the HDD no questions asked (and I didn't buy the machine from Apple). So I come home knowing my Time Machine restore disk had my data backed up but was skeptical of how well it would restore my system. So I started the restore which took about 5 hours (200+ gigs). Just now as I've gotten home I restarted the computer and BAM! Right back to where I was before I took the machine in. Performed absolutely as advertised and absolutely zero hiccups, problems, missing prefs, anything! My music is where my music should be, my pictures are where my pictures should be and so on and so on. I can't say how relieving this is to have "Just worked". I am a 20 year Apple user and am guaranteed another 20 years with this sort of excellent execution. Just had to share.
