The problem with Bluetooth is the stack is too complex. Too many application-specific profiles baked directly into the protocol, which in turn need to be dealt with by device manufacturers. Bluetooth basically handles everything from OSI Layer 1 through 6 at the same time. See: https://en.wikipedia.org/wiki/List_of_Bluetooth_profiles

Add to that great complexity at Layer 1, and constantly changing specs. Bluetooth 1, 2, and 4 are all radically different than each other.

Compare with WiFi, which only has to do one thing (Layer 1-2). Cellular is much more complex, but that's why releasing a new phone involves endless rounds of (usually mandatory and very strict) carrier certification.

The RJ-45 connector is an open standard that can carry basically anything—internet, video, audio, low-level data, etc—at a high bandwidth and with low latency. Why can't we have a wireless standard that does that?

I want non crappy Bluetooth mice that don't require a separate USB dongle. :(

Edit: To be clear, I'm sure ethernet cables are an entirely different thing and there's actually a very good reason why wireless makes everything more complicated. But, well, maybe that's one of the reasons people would like to stick with wires.
