Yes, I think the switch it too big and clunky for a handheld, not to mention the short battery life. They definitely need a handheld only system compatible with switch games but also having smaller games made specifically for it. I specially feel this way for younger gamers 6-12 year olds who are likely to drop the switch, lose accessories, all day playing on and off without having to charge it, simpler more kid friendly games etc...
I agree that a smaller, cheaper & more kid friendly device is a good idea but why would it need games made specifically for it?
Why not just have it be a Switch revision and have those games available on all models?
