I'm shocked that it still has so little penetration into mind-space, since the first surface was wowing people YEARS ago. They have the superpower of being unable to capitalise on their best work!
Maybe it just isn't that awesome after all?
Well, the tech is cool, but what do I use it for?
The current price point means you can't really afford to have it at home. Just like an iPad, it can't replace a regular computer, a gaming console or a TV set, but it's far more expensive than either of that (very much unlike a touch pad). So it's a new product for a new niche, but is the niche large enough to justify the price?
It seems it is something that has a place in a showroom (and that can be commercially viable - maybe it already is? I don't know) or maybe some conference rooms (but at least the first surface was surprisingly small, so maybe not), and maybe some exclusive hotels, bars or restaurants. But it's just not something you could easily place at home.
Maybe it can work well for Microsoft in the contextes it's affordable and works, but it's not exactly a device for you at home.
If it could be had for 700 $ (or even €), I could consider putting it in my home. I am sure there are some forms of new entertainment (or presenting old entertainment in a new, compelling form) that I could put it too good use. But at the current price point, it doesn't work.
