Surprised about Samsung not being involved due to them owning 10% iirc of wacom although if anything I'm more surprised by wacom being involved, they're the ‘defacto’ graphics tablet manufacturer so this would clearly hurt them more than the less known brands.
I'm not surprised by either. Samsung seems to want to ape Apple by “doing it's own thing” even if that “own thing” is worse. And it maybe figures that S-Pen gives it a unique advantage. I've got a Note tablet and to be honest I don't S-Pen much, but if you're a “creative” then I can easily see where it'd be a huge advantage.
Wacom, I would have thought would definitely want to be in on this. The last thing they'd want (surely) is USI setting themselves up as the “competition”. On the other hand if they're (Wacom) are in USI then it's pretty darned likely that they'll be the major player in whatever specs etc are issued. And that's a pretty nice commercial advantage.
Where I'd like to see USI come in hard is for these dual-purpose netbooks/laptops that can also function as tablets. Being able to use a proper stylus (i.e. like the Note, not just a finger substitute) will open up a good few usage cases.
