Article is supported with lot of materials, photos, flash presentations and demo videos, my predications and exception, so if you didn't read it already you should give it a try, it is still very actually.
Thanks to my friend P@sco I've found yesterday an update S60 video demo that is extended with few more applications but to be completely honest with you, all of shown applications looks pretty different on the real device, not sure if it is because of the early proto version od because of the fact that whole UI is still under heavy development and far way from the final product!?!??
By the way, not sure but it looks that Nokia N81 is actually shown in some scenes in this video!?
