Michael Simon, writing at Macworld:
And in many ways, it is. If anyone rushed to Apple.com to buy a HomePod after seeing one of the Grammy ads, they might be in for a surprise after it arrives on February 9, especially if they missed the disclaimer at the end of the commercial: Requires compatible Apple device. More than any other Apple product on the market today, HomePod is indelibly tied to Apple’s iEcosystem, so if you have an Android phone, you’re out of luck, even if you happen to subscribe to Apple Music.
It all reminds me of the early days of the iPod: a high-priced device that only works with Apple products. But while the strategy might have worked back in 2001, it’s going to be a much harder sell now.
Apple Watch required one specific Apple product to work – An iPhone and has done ok, but I can see this not going over well for some people.
