The OS doesn't look well optimized based on the videos. And what is the white curtain that comes from the top?
Why would you say that?
In the video all seems to be rather smooth and fast. So I would say it is well optimized for the limited CPU and memory inside.
If the UI is a good fit for this form factor is a different story, and can't be judged based on the video I have seen.
The big question is how well the low-cost resistive screens functions, and if the relatively small screen is a problem for the UI interaction with this touch-only form-factor.
I've said it before, but if there ever was Linux based "Meltemi", it has surely be killed by Elop and Microsoft (and NSA) and those Ashas are with S40 based "Meltemi" = "Nokia OS".
Windows Mobile -> Windows Phone
Symbian -> Nokia OS
Nokia even think like MS now. When your platform is dying, change the name.
Nokia OS is the well-established name for what's underneath the S40 UI. This is not a new name and it has nothing to do with Symbian. They did change the name for Symbian, though: It's now Nokia Belle.
