Frickin' earbuds. They don't fit my ears AT ALL-not even when sitting. I really wouldn't mind if they didn't become standard. What really annoys meis when the world acts like the problem doesn't exist, like when I see marketing materials for things like the ear clips that fit standard Apple buds say things like "they work just fine when sitting, but what about when working out?"
The in-ear type work fine enough. Why aren't those standard with audio equipment? Of course you can use your own, but when the iPhone launched it wasn't an option due to the design. WhenI got my Sony MPD-AP20U (hard to define), I was expected to use the in-line remote with the extra-short buds it included. Using anything longer was a nightmare.
