Once they do this without the need for a host PC I'm sold.
The disk selection could be implemented in a myriad of ways. Nobody said this should go exactly where a diskdrive is. It's not a diskdrive after all! I'd happily have an LCD display and buttons built into my Amiga's case, like atop, where the vents are. It would be very convenient.
SPS use is probably welcome to some, and a great breakthrough, but I grew to the point where I cannot care about floppy disks anymore at all, and preffer a WHDLoad install to anything. In any case you always end up needing a floppy so this will be a great tool once it's rid of its PC slave.
