Throwing good money after bad

I read on Rocketreach that Spence is not only the Big Cheese but also Mr Money Bags.  Let's hope he's got his Texas Instruments calculator at hand

Yes, and there is informed decision making.  There are plenty of people having no or little issues with the app.  For my part I use Alexa to start / stop music through my six zones.  It’s down to individual choice.  I wouldn’t presume to tell you that your purchasing decisions were correct or not.

Well, once they half-fixed the musical alarm clock feature, the complaint totals fell away dramatically.  Now, there are poor souls who have bought into the ikea Symfonisk dream & are left sitting with a silent piece of plastic and cloth which won't install.  

Well done, Sonos! 

(ps: I've got a Symfonisk Frame which works) 

Meanwhile, how's this for cracking software performance?
