>>6You kidding?
Phones are ridiculously overpowered.
iPhone 7: Quad-core 2.34 GHz CPU, 2GB of RAM, PowerVR Series7XT Plus (six-core graphics).
Samsung Galaxy S7: Octa-core (4x2.3 GHz Mongoose & 4x1.6 GHz Cortex-A53) CPU, 4GB of RAM, Mali-T880 MP12 GPU.
You think you need all that shit to make phone calls and use shitty apps?
If they were restricted to a 700 MHz processor and 256 KB of RAM they would get the same functionality (but with better programming languages, more optimizations, less wasteful crap, etc...)
