I am new to Mac, I don't even have one yet but will be buying one soon (holidays) so I am learning everything I can about its features, and there are many. One thing which really sounds great to me is Autosave, versions and resume introduced in Lion. However when I try to find out who actually uses it, besides Apple's own apps, I am dismayed because it seems most apps don't. e.g. Office, LibreOffice, Scrivener, a bunch of mail/note taking apps etc. Most of these implement their own save system. I also found a bunch of threads (here and on Apple forums) on how autosave is not useful in practice - is this true? For a feature so old, I thought it would be widely adopted. After all that is one of the main strengths of OSX AFAIK.
