The issue is it's the default and many people (myself included) would not know of this right away. I didn't know that the option was to make subdirectories that didn't need to be made. I only found out when I first noticed the subdirectories on my 650. I've since fixed the problem. But I bet a lot don't know and the more they use Calibre to put books on and the device to delete, the more empty directories there are. I can see the device slowing down as it has to check each of them to see if there are books.
Yes it can be changed. But it has to be noticed it's there and what it does. I think a lot of people who do see the options for sending to the device and just leave it alone.
If it wasn't the default, it would not be an issue (IMHO).
