I gave in and got one (UK). It has a startlingly perky voice and it knows my name, but the web interface is compounded with all my other web activity, you can't feedback via cards as with Echo, and it doesn't have a
Fact du Jour. Nor did it have anything like the answer to 'Who is Dr Who?' Alexa managed, but it sings a better song. Lights on the top remind me of iDogs and it still looks like an air freshener.
Only had it 2 days so I'll try to come up with a better appraisal when we've got a bit more used to each other. What should I challenge it with - suggestions?
