If there is going be insistence on platforms being open there shouldn’t be these distinctions.
All of these devices are capable of general purpose computing at a hardware level, phones, tablets, PCs, headsets are now very similar and generalised in that regard. I don’t see why a phone platform should be forced to be open while a games console gets to remain closed, when there is now only a hair’s breadth separating an Xbox from a Windows PC.













The N-Gage had a bunch of bizarre design decisions.
The game cartridge slot was behind the battery - swapping games required disassembling the phone.
The revised QD version fixed a lot of the mistakes but it was too little too late by then.
