It is my impression that the complexity of the sync and tile based
user interface hobbles the performance of the AuraHD. It could be
much of the reason that the 1000mHz Aura can't handle the number
of files or a file structure of any real complexity, when compared
to ereaders using much less powerful 400mHz CPUs.

The power and potential of a database derived user interface may be
very alluring and the "book management" as opposed to file management
concept may work well for calibre, but a simple user manageable file
structure would allow for a higher performance with large ebook
libraries.

Just as when trying to make a high performance racing vehicle, a
stripping out of any extra, unnecessary weight, is an essential
step. So much that appears to be there solely to tie use of the
device to Kobo servers provides nothing to the basic reading
functionality of the device.

I know nothing of how the FW is structured but I do know that some
modularity must be there. Would it not be possible to unentangle
the reading and just those other components necessary to support
reading, from the current mix. Then remove the current overlay of
the file system and allow for the normal file management of the
partition's format.

I realize this approach would not be popular with Kobo, but it
would be just the thing for many of us users.

Luck;
