Reading your post got me to thinking. I've just had a vision!! I've got it!!!!!
The brick could be a module that is removable from the MacBook itself. Instead of putting the laptop into a dock, you dock the brick into the laptop! This way, you can bring all that extra stuff (optical, usb ports, what have you) if you so desire, but you can also eject the brick and have a much lighter laptop!
Whaddya think??? Have I figured it out or what?![]()
No you didn't. Basically you didn't provide an explanation as to why having it being PART of the macbook is better than being just a dock. In both cases, you will leave the extra weight at home or carry it with you.
