All I care about is an improved desktop experience, and they spent hardly any time on it. Cortana seems more like a privacy nightmare, than a helpful tool.
Even the tone. There’s no electricity or excitement at all. You think they’d learn something from Apple by now.
The only substantial thing I’ve heard so far is it’s a free upgrade from Windows 8.1.
Update: The holograms are interesting. Not necessarily exciting until they’re proven, but interesting. In the Holo Studio demo, the first thing I wonder, is why does she have to point and pinch at a distance, instead of just walking up to it and grabbing it like in real life?
