So at the end i still think it is only good for floppy tinkerers.
Well, with this there is no need to tinker with floppies anymore, that's the point.
Notice that this device is not just for amiga, it can be used with plenty of machines, machines that may or may not have used weird floppy drives that are hopeless to find in working condition today. It is a great thing to have around when you need to bootstrap a system, be it amiga or atari or whatever. A bonus for us minimig tinkerers is that we can test adfs on minimig and real hardware from the same SD card
