That's the last thing manufacturers want. They saw what happened to the PC hardware market, which was basically a race to the bottom on price. If they can do ANYTHING to differentiate themselves from each other they will, even if it means they have to support hardware themselves. Unfortunately they want it both ways, selling commodity hardware with a "unique" wrapper.
IDK, different laptop manufacturers can differentiate themselves pretty well, XPS,Thinkpads,Elitebook,etc all of them have a reasonably well defined market
