OK-
Sure- we can design and manufacture *something* today or lets say tomorrow,
because today it is a bit difficult. It's only being designed today. It still
has to get the support, the money, the manufacturing, etc. But even once
you've got that your still missing a graphics chip, a wifi chip, etc.
We might get lucky with next generation graphics on ARM. Which might leave us
with just wifi to fix, but that is still a huge problem. Reverse engineering
isn't cheap. Do you have $100,000 to fund one person to work on it for a
year? It's a skill set that pays very well. You might think people should
work for nothing, but reality tends to get in the way if you want stuff to
get done. Most free software is paid for by somebody whose got an interest in
its existence and in some way is making money off it. Whose going to make the
money off reverse engineering a chip when the people here have evidenced the
fact they're not willing pay a premium for something they can get elsewhere
for less?
