Another: why didn't they add feature/spec XX? It only costs a few cents/dollars. Or it's easy to do.
Yeah, 5-pin MIDI jacks only cost what, 50 cents? (not realizing the additional electronics required). Or wanting to be able to send a different signal to the headphones than what's going to the main outputs (no, it's not just software, but would require a whole separate audio output chain).
And one more - "They shouldn't have put the Pitch Bend and Mod wheels so far back, they should be closer to the keys." Those wheels aren't just sitting on the surface: there's a whole rest of the wheel which needs to fit with the keys extending behind the fallboard.
