I'll certainly grant that... but the price point where Mycroft is, is certainly not near what I'd pay for doing those few simple tasks.
Apple is at the upper end of what I'd spend for such a device (the HomePod mini is $99) - and that's because I'm fairly invested into the Apple ecosystem and thus it can make use of the iTunes library, home automation, calendar items, etc...
If I wasn't invested in Apple, then none of the home assistants other than Amazon (because of the price point for the echo) would be particularly interesting.
I've got a echo show - because its a very nice simple clock/weather interface (that's got Alexa behind it) too (I really liked the Ambient 7 day weather clock when it was available). I've got an echo wall clock that is paired with the echo in the kitchen - it makes timers nicely visible (a sibling of mine has an echo wall clock because its an analog dial that doesn't have any sound with it).
The problems with Alexa of suggesting by the way ("Alexa, stop by the way" - give it a try and yes, it is routineable) are tolerable for how much I'm paying for them and the functionality that I use it for.
