Yup, my parents had many in wall / ceiling speakers wired up to a receiver that they sort of forgot about because the system only received input from a 30 pin ipod dock and no one ever bothered to figure out how the receiver was configured. I pulled that interface out and replaced it with a chromecast audio and it blew their minds. It was probably the biggest ROI I've ever gotten out of any tech project I've ever done for them.
I'm very sad they are discontinuing this product. I was actually about to buy one for my new apartment. It looks like they are sold out everywhere already :(
This was one of Apple's great inventions, it became widespread in hotels, every base station used it - so having achieved massive adoption they obsoleted it.
