This is the most obnoxious end-of-life decision.
Clearly the world is not going to base its OS upgrade decisions on the compatibility requirements of your products. Reasonable FireStudio Mobile owners who upgrade to Catalina are now stuck with an expensive paperweight. Worse yet, the environment is now littered with yet another piece of electronic junk. A responsible company would offer to recycle these devices in exchange for a discount off the modern equivalent of this device, which is what - a 26c?
But instead, on principle, we have to look elsewhere for a replacement b/c we feel cheated by your decision not to upgrade this software.
This stuff looks pretty good.
