What I'm saying is it will be called by whatever moniker they choose to call it, but I believe it is inevitable that Apple changes their entire mobile lineup to thinner and kill along with it certain ports in order to do this. EVENTUALLY they will kill off the 3.5mm audio jack as well, again EVENTUALLY. Now? Probably not. It just seems like the writing is on the wall.
Who is to say that a "Pro" level laptop cannot be redefined so as to include more suitable external solutions while keeping the laptop/notebook itself in a slimmer design? Heck, Apple thought so with the Mac Pro desktop.
Yeah...they can redefine it to the point of what exactly?
External Gpu's such as with the Razor are all well and good but they're not really portable and are for gamers basically.
There will come a point of form over function for apple, at that point, some user's who need power will jump ship..but they'll be replaced by more who's need's are less I'm sure...
