yes but most people would need a desktop because of the work they need to do , but also need a laptop when they are out and about for presentations and such , so dont necessary need a battery most of the time anyway ,but the cant or don't want to afford both laptop and desktop and try to fid a compromise and thats a relative high powered laptop like the MBP , so they would like to see the laptop with the same or even better performance as the desktop , which is just not possible , there only had been one good compromise found so far
this one
ok its a portable desktop with 3 displays that fold together for easy transport , and can take a full atx board and full graphics cards , downside weights 15 kilo , but still portable , but i think its a great idea , full atx means exchangeable parts , why apple cant make something like that out of the MacPro i dont understand i find it great and would certainly buy it over a iMac 27" and a MacBookPro , as most of the time i just need something portable but not necessary with Battery , from here dover in the car and then to my flat in germany all i would ever need , no multipe screens to store separate always with risc of breaking them as they are protected inside
and i like the 3 display layout as i love multiple small screens instead of one big one
