the drag-a-window against the side of the screen side by side view is so useful it's ridiculous
This is the only feature I've seen in demo videos that looks like I might actually use, but even so I would probably only need it occasionally. What other features are actually useful?
How is Pin really any different from QuickLaunch? And I don't really care about preview windows in my taskbar, I know what I'm running and where my files are. Likewise I don't care terribly about synching my media with other devices.
Then again I did hold onto Win98 for a loooong time after XP came out because I didn't really see much reason to switch. And honestly - aside from software compatibility - I still don't. Other than it looks nicer.
