"Because it would make piracy super easy."
why would that be? if its sold on their own designed game cartridges. Why would it be any easier to pirate than any other devices?
(sony could have made cusom ARM cpus from AMD, so the software only works on their phones, due to a co-proccessor or some such unit that normal smart phones dont have = solution to piracy of their software, hell they could even make a custom OS, thats differnt from other OS smart phones have.... again = no more piracy issues then).
Also seriously a device like that would be really attratice to alot of people.
Sony could charge a pretty penny for it, and more than make up for any potential loss due to such.
Look at apple, most of their profit is from the hardware side.
Make good cheap software, thats easy to buy, and make the most of the profits from the hardware sales... it works for apple.
