It is so funny to read all the useless speculations. We have had some good vids where both hardware and software are shown. The rest of the specs will come later... so be happy for now.

Beautiful design, clever in its set-up, so that a back cover can change colour, functionality and add hardware !

No use to gossip or to 'demand' or to be 'disappointed'* in functionality that surpasses the price, the design idea and the software development (for now).
Just try to understand the concept; "The other half" & "Unlike", the open way software partners are encouraged to participate etc. etc.

For now I support the tweets that demand: "Take my money now !"

* All those mobile hardware engineers here that think the bevels are to big Tell me, where do you suppose the hardware should go ? Specially the hardware that can be added by the back cover ?
