The sad fact is, that it will never happen. Most companies will not spend the time/money to innovate or create new hardware/ custom chips. They will continue to build boxes with off the shelf technology- it is way cheaper.
The netbooks tried to sell with linux, and the public demanded they have Windows, even though the linux boxes cost less. I know when the ASUS EEEPC came out, all my customers wanted one and paid me to put Windows on all of them, even though they only had a 4 gig hard drive. We sold over a hundred, and NOT ONE customer would even TRY the linux install.
So the MASS public will continue to demand Windows, because they are familiar with it.
That, in a nutshell, is why in the last 15 years, linux has not taken a lead over Windows, and never will. That is also why a custom chip/ hardware computer will never outsell an X86 or ARM processor box (and the only reason the ARM is gaining ground is because people have no clue its not X86).
Companies will only take chances on proven and cheap technology, that they know they can flog to the average joe out there. Plain and simple.
