Andy Robinson, the deputy editor of gaming website CVG, was just one of the experts that felt that one area that can absolutely not be overlooked is the phone functionality itself.
"I think the PlayStation Phone needs to put its focus on the latter; phoning people up," Robinson told TechRadar.
"Nobody wants to buy a PSP with a keypad — core gamers especially.
"Sony should make a proper, feature-complete mobile and then sprinkle in some PlayStation hallmarks, such as the trademark buttons (even if they're on a touchscreen) and PSOne classics to download. Oh, and a digital store this time, please — no UMD mischief."
N-Gage: Ahead of its time?
Robinson's words were backed up by Kieran Alger — the editor of T3.com, who admitted he feared the worst.
"When I hear the words PSP and phone put together I have horror visions of the Nokia N-Gage — the big, beastly pocket pummelling N-Gage," said Alger.
"If this needs to be one thing, it needs to avoid being a brick. The iPhone gaming revolution has been driven by casual gamers, people who didn't really know they liked chucking avian objects at swine.
"For me serious gamers like to do it on bigger screens. The middle ground could be a scary place to be.
"Above all I'd like to see this be a good smartphone device and not just a PSP that makes calls."
