that's an absurb statement.
a very-small percentage of macusers live on this forum (most live in the real world). how many macusers don't use time machine? i mean, if you're reading about people with issues with TM, here, on this forum, that's a tiny percentage of the overall user base.
i don't use TM, but, for 99% of macusers, it's both essential, and simple. and works.
Just discovered TM and I love it. Always used CCC before and I will keep doing so because it's a great app, but having additionally TM enabled is awesome if you just want to go back to replace a single file from one hour ago.
Also that makes it so much easier for people who refuse to think about backing up their data at all.
I could never convince my mom to back up her iMac with CCC while having cereals once in a week.
