They mentioned that being a small screen touch can be tricky so that a keyboard and mouse option is actually easier, which really makes sense to me as you are displaying Windows applications which are not designed for touch.
In that case they should run touch-optimized programs. Such as Bitwig or Gig Performer. I think it's looking pretty nonsensical in that presentation. I'd rather use a proper laptop instead. Unless the unit was supposed to sit on the floor. But in that case, proper touch navigation would be a must. So that's a full circle already...
Not sure what you mean by "not a mobile Windows version."
A version that becomes more touch friendly. Such as what you find on convertible laptops. Not sure it's doing that already, certainly doesn't look like it in the video.
And, I've read somewhere that it's an N200 CPU (not a very capable computer), with an USB audio interface connected internally (via USB, I mean) throwing around 7ms latency.
That's not even remotely decent then.
For me, it's still much worthy an average laptop (I've got a 300€ one that would wipe the floor with the CE1) with a midi controller and an interface of your choice, if you want a computer based rig.
Well, bringing a laptop to a gig is causing headaches for guitar players. Been there. "Where to place the thing?" is where it all starts. And it's not an easy question to answer.
The keyboard has to be protected at all costs, because once any moisture is spilled over it, you're done. Yeah, there might be some protective layers, still allowing you to operate the thing, but I haven't seen much (if any) sufficient arrangements of any such a setup - at least not for guitar players.
Your best bet might possibly be a Macbook Air or so, that you could just boot, then start all programs you need, then close it and place it in a rack drawer. All further edit actions would have to happen remotely.
And while such a setup certainly is most promising, at one point it'll also start to become at least somewhat expensive. You'd need a quality audio interface, a floor controller, cases for everything and what not. Then add at least some software.
I calculated what a rather cheap-ish setup of that kind would cost me and it'd defenitely exceed €2k - sure, one could buy a refurbished Macbook and other used parts, but for such a kind of experiment, I'd prefer to buy things covered by warranties.
This is why I'd be sort of interested in a ready-to-roll device, but so far I haven't seen anything I'd really consider decent.
