Nexus One works with Apple headphones with inline remotes!
Unfortunately, the volume up/down does not work, but that's basically exactly the same as using Apple's newer headphones with last-gen devices like the iPhone 3G. Given the fact that the other stuff works, though, it seems entirely feasible future Nexus devices will enable volume control this way. Overall, though, I'd say this is pretty nice -- especially considering most companies just opt to build their own lame inline remote interface that sometimes isn't even used on more than one device.
i'm just glad to know that the headphones i have for my iphone will still have a functioning mic if i make the nexus one switch. my 3gs pair i leave in the car, the pair from my 1st gen iphone is my back up and a set of Nixon Whip with mic that stays in my backpack.
in a world where the thought of switching devices so easily becomes a switch in which accessories go with said device, this is a welcome change.
Just something to keep in mind if you find 2 audio apps playing at once.
