Why don’t people play handheld games nowadays?

Every time I am in public, all I see is people using IPODS, Cell phones to text, and just reading but nowadays, it seems like nobody plays gameboys or handheld games anymore. Why is that? Its like it will be so weird and odd if I saw someone on the bus or in public playing a handheld game or a game boy. Would it be way out of date if someone was still playing a video game now and not texting or using newer technology in public? It seems like that kind of stuff is obsolete now and too old fashioned. Right?
