A gaming only handheld has been gone for years, the last one I can think of would be a GBC but even that could have a camera attached to it, GBA had mp3 and movie playback via game cart expansions and everything since then has come in leaps and bounds in terms of Native movie playback, Internet browsing, online game stores on the device, music playing software, skype calls, mobile text messaging on the vita even.
All that's left to be added really to "gaming" handhelds is the addition of proper phonecall (not skype calls) on what is being refered to as a gaming handheld and the only remaining difference is where their key focus is, gaming devices start with controls and a screen for gaming, small mobile device touch screens will never rival that for more than angry birds and endless runners.
