We use Meraki MR/MX stuff at our office and are generally happy with the value & service. The MS stuff though, thats another story. Do you guys have plans to enter the sub $2K tier with L3 devices?
I haven't worked at Meraki since 2015; sorry, can't help you out on that one.
I will note that as of 2015, "L3 switching" (i.e. hardware-accelerated IP routing) hardware was expensive as hell. I believe that on the software side, dropping new hardware into the existing hardware-routing infrasturcture is fairly easy, but I don't actually know because I didn't work much on MS hardware.
