It seems we hear a lot about Sony's plans for this or that, but the PSP in particular is subject to hopeful speculation and encouragement.

Now rumors of Playstation entering the phone market are beginning to bubble, perhaps even by making the PSP itself into a phone.

Of course, it's not the case that you can connect to wireless LAN everywhere, so you can't call it a permanent connection. But cell phones are permanently connected. Cell phones get more interesting as their data transfer rate increases, and I think it would be extremely interesting to try something like that."
