I can't see that using Alexa is so very different from using a computer; it just seems more personal because it's voice-activated. I like the convenience - I was looking at holidays on my tablet yesterday and just said out loud, "Alexa, what's the flight time to Tblisi?" and got my answer immediately. I could have googled it, but Alexa was quicker and easier, and saved me losing the page I was looking at.
I have ordered a second Echo Dot (they're back down to half price again!) for the kitchen. I intend to replace my kitchen radio with it, as it will be much easier to use a voice command when I'm busy cooking, with messy hands. It will also future-proof my radio listening, as FM radio is due to be switched off in a year or two, and I don't have a digital radio. Then if there's nothing much on the radio I can ask Alexa to play music for me. It might also be handy if I want, say, to convert oven temperatures or ask how long it takes to cook something.
