PSP and Portable Gaming Becoming a Dying Breed

Dustin @ Ps3Center Writes:
The PSP Go launched recently, boosting PSP sales once again to become a high end PlayStation system. However, Sony has stated several times that it's the best handheld system on the market. When they reference this, not only are they targeting their rivals Nintendo, but the market as well, which is beginning to open up to Apple and Microsoft. Neither Apple or Microsoft have truly made a portable gaming device, but they both believe that their new gadgets can in fact steal some of the PSP's future consumers. So how will this turn out? How will the PSP fair down the road? Does Apple truly have a foot in the game industry? And how is the portable gaming market slowly becoming a thing of the past?
