For many years we announce in personal conversations that someday there will be the point, we stop offering postal delivery on HD floppy disks because diskettes are no longer manufactured.
Now the time has come. At the end of 2016 we'll stop this service.
For a log time we considered whether we want to use USB sticks (or others) as data carriers or not. However, this is not very sustainable.
First, USB sticks are expensive to buy, so the shipping costs would explode. We would also use only a fraction of available memory per shipping process.
We are a bit sad but the floppy disk accompanied us longer than expected.
