If that ever happens, it's a long, long way off. People who buy handheld consoles do so because there are certain games you want to play with something made specifically for games, not a device with gaming thrown in as a bonus. Analog sticks, button placement, size, and lots of other stuff is kind of important.

I expect the lines between smartphone and handheld consoles will blur, but there will always be devices where gaming is specifically the #1 purpose, and there will always be certain games made specifically for those devices.
