Wow lots of questions...
It's made using 3D rendering software, which is pretty easy if you know your stuff.
Yes I made it, and it only took about an hour or so! I have a load of my designs at http://www.techno-*********
My thoughts on the software/hardware:
I think it will be a new OS. A cut down, multi-touch version of OS X that relies much less on icons and windows. Much more of a 'natural user interface' using gestures and such. There are tons of solutions for keyboard input instead of having to use an actual keyboard.
I also assume they will include a 'swivel mount' which they patented not so long ago. I may mock up a design of the mount.
Speakers and charger will all be at the bottom side, just like the iPhone.
They could include the new 'wireless' charging docks that have been in development recently. You put the NetBook in the dock, and as long as it's touching it charges!
I think I may include a couple of ports to the design too. Maybe a USB, video out, headphone & mic port.
These things would be perfect for using iChat on the go!
