Ambivalent here, too. I watched the video at your link, with it's 10 reasons to upgrade...and didn't see one thing that mattered to me. The only reason I might be tempted to upgrade is simply to have a fresh OS and possibly clear out some crud from the Registry. But Windows 7 has been rock solid, does everything I want, and runs some specific software that is not yet compatible with Windows 10. I appreciate their offer...but no thanks.
