I care. I like that I can just tell it to play whatever song I want, and it starts up a whole playlist based on that song. How's the weather tomorrow? What's the news? Turn off all the lights. Turn the TV on and go to this or that channel. Where's my stuff (amazon delivery)? Set an alarm for 5AM. Set a timer for 15 minutes. Play this or that audiobook.

List goes on and on. I know it's all the rage to hate on these things while the cellphone on your desk carries all the same vulnerabilities, but I've found them to be pretty convenient in a lot of ways.
