Is it a patent issue?
I was wondering why Sony hasn't added touch screen functionality to their PSP.
I was also wondering why Sony and Microsoft haven't added a pointer system to their controllers.
Sure, most people will say "we don't want that", but look at how great it works for the DS and Wii. A touch screen is great. Pointer > motion control. Companies could port their Nintendo-exclusives to the other systems.
So I kind of thought it has to be a patent issue. Does Nintendo have the patent on a 'gaming controller which incorporates an IR-pointer technology' and a 'handheld gaming device which uses a touch screen for input'? (Of course there is the iPhone, not sure how that works.)
Your thoughts? And if not, what other reasons do they have not to include it?
