"I don't think it takes a power user to understand how Versions works. Actually, most people complaining are power users because the system is saving for them."
No, you don't need to be a power user to understand how it works, but it does seem that you need to crawl into the mindset of a half-wit to see why it is now universal. I can tell you one use case where it does not make sense and it hinders performance:
I have large Numbers financial documents, that are paired with very large Pages financial reports (200-300 pages). Both are password protected (think in terms of 30 characters or so). Now, when I open a document, I do so knowing what I want to do with it - I don't need a "locked" document. That is just silly. Now then, with several documents open, and autosave interrupting about every 5 minutes to slug out the most minuscule of changes on my SSD drive, that really ticks me off. And what also ticks me off is now I have many versions of password protected documents - absolutely useless. If I keep my documents open for a 12 hour day and actually use them as I do that is 144 minimum password protected 300 page Pages documents that I have no idea where I made changes, as I do so throughout; and even if I did, I don't really like typing in a 30 character passwords to see each one and then scroll through each one to see if it that is that special one.
And I do question where the so-called "delta changes" are being stored. Are they truly secure? It really doesn't matter because the whole thing is a mess. What really ticks me off though is that I really don't have an option to go back to SL since I also use the platform for development - guess what platform is the best to develop off of, - right, the most recent. Given the humongous oversight of Apple in regards to this issue, it really makes me question their "progressiveness".
I can live with the fact that Launchpad, the dock, the application folder in a stack, and Finder / Apps are four ways to get at the same thing...but I get to choose. Why Apple thinks forcing users to automatic save and versions is beyond me and I wish people would quit trying to blow smoke up my backside and tell me it is sunshine on my shoulders.
But - again - in reagrds to autosave and versions, sInce Apple seems delusional in their approach, I will match with approprate quote: "If a change is made that is large enough to alter permanently a long-term trend, then the consequences for the society as a whole cannot be predicted in advance" (ted kaczynski, manifesto).
If autosave and versions are not corrected, then I am looking at a major change in the way I do business and will be looking at other operating systems (from other vendors) and leave Lion (currently aka Apple's Vista) and Apple for good.
