I would love to use hEX lite asap. It's a total replacement for RB750.
But what's the reason if there is 941 exists? Despite its 4 (instead of 5) ports and lack of PoE, it is capable router for such a great price! And I wait for "full" 941 model (PoE, SPF, 5 ports) - that would be the killer!
By the way, why not just to create one good device with 5 (or even
ports, with WiFi, with powerfull cpu and produce it?
I understand there are situations when you do not need WiFi router but you can easily disable it. But at the other hand the price difference isn't too big and if company restricts itself to only several devices the price may actually be even lower.
Another point is that if we talk about only serveral models it may be easier to test ROS on them and be sure no h/w bugs are there.
