Over here the carriers rule the phone industry. Americans don't buy cellphones. They buy service and their choice of locked phone comes with it.
Hardly that. It's the fact that our networks suck balls. There's also the fact that much of our living isn't intertwined with the cellphone.
The US has no FeliCa tech. That leaves out using your phone as a train pass/airplane pass or making purchases with your phone. Also leaves out the ability to open doors or start your car with your cellphone.
As our networks suck, anything dealing with bandwith comes at an additional cost. So might as well cut out video calls.
No one bothers with having barcodes that can be scanned with a phone, which would then link the user to their website. Hell, I have that setup with my MS Live.
No TV services. Japanese use 1seg. Only other country to use 1seg is Brazil.
Until Americans start beefing up our networks, we'll never see anything like a Japanese cellphone.
