Jabes-
First off that article is a lot of fluff you linked. Yes Time Machine does have its bugs but what Apple is trying to do no one has ever done in a consumer OS. They are trying to make back ups simple and easy. Time Machine is not a true snap shot system, instead it uses hard links to files instead of soft links (symbolic links - use wikipedia to look them up). Time machine is an end user product not an enterprise level back up product. Under the hood OS X users could already use rsync from the Unix command line and set up cron jobs to automate back ups. However, not every user is unix savvy.
I could list all the vista bugs here it had at release but it would take up pages and pages of this forum. All OSes have bugs when they are released, and yes every major release of OS X from 10.0 to 10.5 has had bugs, just like every version of a Microsoft OS sucks until it hits about service pack 2 or about.
And in your sig you say that anyone who hates vista is a noob? i hate vista and I am willing to you are a total noob compared to what a lot of people out there really know, and experience. The ZDnet guys write tons of crap as well. I mean he talks about NAS and time machine and doesn't even realize that it uses hard links to files over a network share, which the new version of AFP allows, so you can't use any other share than an AFP. This is because not every file system treats meta data the same and this is not Apple's fault by any means.
It is really just a misinformed article misinforming all that read it. That is why I hate professional tech bloggers, because they are journalists and not actual technology people.
