Indeed, i help with going on and on:

The rounded caps are super comfy and the pressure point is on spot. I had the direct contrast when failing to put my long wifi pw into one of the demo devices via virtual keyboard since it did not come to mind to flap out the qwertz. It just feels like a normal, a bit thicker phone of that size. Then Erik smirked at me and my brain froze a bit realizing i am typing on virtual kbd on a Pro1 first time i touch it.
Entering via Qwerty was so nice, no hitting the screen on top, much space to hold on and not let it slip.
The angle is a great help to not cramp your fingers. Much better than on N900 where i always lift/angle my hands up to get the screen in good position to my glasses. I guess that was one advantge of N950/E7 already.

And the fri**in slide out is satisfying af. (sorry for the language i am really hyped that my expectations got over-delivered). The videos are one thing, you have to feel it.
It snaps in place as if an overpaid sound engineer spent a month on that confirming and worthy mixture of a "Whoomp" & "KLACK".
If you ever wanted to envy an iphone user, simply klack him away.

Ohhh and the screen. It was the brightest day a german can imagine to test sunlight readability and the pro1 did shine. (No i am not going to over exaggerate by adding "like the sun ")
Go to a phone shop and look at the Note series. That is the pro1s screen as Adrian explained. (forgot which Note).

Ahh and quite loud stereo speakers.
Uhh 3,5mm jack.
Ohhhh the camera is not higher than the main body but ~0,5mm embedded.

But most important, and the reason why i invited them in the first place. I could feel their enthusiasm to work and how serious they are about the device Quality.
Have seen a lot of startups from within and seldom had the need to describe them as well organized and completely sane behaving.
I now wish them to find a good compromise between further refinement and "go to market". (Thanks @Olf for the lengthy discussion about that topic!)
I lean towards it being perfect for me and want it NOW

Thanks again to all attendees for the fruitful exchanges. I learned a lot today.
