Yes, it would be remarkably cheap to make a GBA quality device with let’s say 2 GB onboard memory to store games that had WiFi and was download game only.
It would be EASY to make a $60-$90 device to do this.
I would be very excited for a very cheap gaming handheld with a solid screen and solid buttons. Too bad no one wants to make it for me.
Sony and Nintendo need to give up doing the ‘non-game’ functions like ‘Internet Browsing’ or ‘Netflix’ on their gaming handhelds. Smartphones are handheld computers. A gaming handheld should not try to be a handheld PC. Just laser in on the games.
