It's still difficult getting hold of a Raspberry Pi - especially if you need a Pi 3 for an existing design. So, on my recommendation the company I work for have switched a design to use BeagleBone Black instead. It seems to be going OK so far. This sort of hardware is not our core business and it's not a particularly demanding application, but it'll be interesting to see how it goes.
As our development team are very familiar with Microsoft's .NET, it'll be running a .NET Core - which works surprisingly well if you want cross-platform (i.e. Windows and Linux) stuff.
