I basically don't care so long as the PSP2 is as powerful as rumoured (Tegra 2 etc).
I'm also failing to reconcile how the above image of the PSPhone will accommodate the rear mounted touch pad that has been circulating about the PSP2, it doesn't seem feasible in that current form factor.
To be honest, i just want a PSP2 with a 3G data connection so i can download stuff anywhere i want, i already have a phone that does everything i want it to do. Making the PSP2 into a phone means compromise, either make it small so its pocket friendly as a phone device or make it large to accommodate a bigger screen and help heat dissipation of more powerful internals.
Sony, just make sure the PSP2 has a 3G connection, PLEASE.
