Sure, why not? Like I said, I really do want to know what this software can do me, even more importantly than what it can't do for me, but no one seems to talk about that stuff.
My point being, what , if anything is there that would make me want to upgrade. I mean, it's free, that's a pretty good incentive, but if I end up just having it sit there running all the pretty-shinies and it's not really doing anything, that to me is annoying, and more to the point, if I don't use or want to use a functionality is there a way to disable said functionality so it doesn't steal processing power, etc.
Honestly, I'd stick with W7. I enjoy the new and shiny, like networking all my computers and consoles, and like having voice control over it all. That's what attracted me. Otherwise, W7 worked just fine for me. I guess for me, every step towards Star Trek where I just walk into a room and tell the air what I want done is a bonus, but if that's not your thing, then W7 is just fine. It's why I like Apple stuff, too.
