But... If you are not a "geek-type", what are you doing on "Hacker News"?
The fact that everyone said the same thing about Unity and are now coming around to it, proves my point. I happen to love Gnome-Shell. I don't mind Unity and I think Win8 is great after you take some time to get used to it.
I think Metro for desktops and notebooks makes very little sense unless you use a multi-touch pointing device like Apple's trackpad. With a mouse, it's painful.
And it doesn't completely answer your criticism but many Synaptic touchpads for a looong time are multitouch capable, they're just not utilized. It's different, I'll grant that, I didn't think it was painful, but I adapt quickly and I don't mind scrolling with the wheel to move horizontally. (The proverbial) You get used to it.
I get it, despite being in the tech world, geek-types remain incredibly resitive to change, but I'm tired of every tiny change that Google or Microsoft makes turning into "they're jumping the shark".
