japanese phones were buggy, feature packed monstrosities. a bunch of companies fighting to check as many boxes as they could. it's not a surprise that they got wiped out by an attempt to make a holistic internet communicator.

Everything got quickly walled off soon after, and for two decades we were left wondering why it wasn’t possible to share a picture from your phone to your computer, both BT-enabled, and instead must use proprietary protocols like AirDrop or convoluted steps in Windows.
