nobody is defending the 7000, my suggestions for improvements were in before anyone elses.
We are discussing your feeling of being misled through citing a list of things most of which had nothing to do with your original question.

If asked the question does the 7000 handle long file names you could write another list which actually answers the question.

the 7000 handles:

current panel
panel memory
sequencer
composer
sound memory
performance pads
effect memory
user midi banks
favourites
home page
all custom styles
individual effect memories
individual sound memories
individual songs
composer banks
individual composer memories
pad banks
individual pads
panel memory banks
individual panel memories
folders or directories
files or songs
midi files
midi playlists
midi song medley folder
midi song medly user list
audio files
audio playlists
favourite songs

all with long file names. err... quote "just some minimal support in limited areas".

You did not ask how long file names are created or what happens to them on floppy. If you had actually asked these different questions no doubt you would have recieved an accurate answer.
Enough said.
