Also the Japanese had very advanced mobile networks from very early on, so I assume there were some pretty smart devices (for their time) much before smartphone

  As far as I know, they had 3G networks way back in 2001. They were the harbinger of profit for carriers here in the US. I remember the carriers were not enthusiastic about putting billions into upgrading their networks to support the faster speeds unless there was some way to monetize it. Thankfully, when news started coming in that NTT DoCoMo was making tons of cash off of data streaming and text messaging, then the carriers were all in.
