A few more things:
-- Xpad is a very good replacement of KNotes.
The original KNotes is running not fast enough. Then I use Xpad, which runs much faster and eats less memory than KNotes, and it can even be automatically docked to the panel as an applet along with clipboard. Double click/tap it will open a new sticky note, which comes very handy.
-- The PIM apps as separate packages?
I wonder if the road can go further down by stripping away the KDE pim stuff (KOrganizer, Kontact, etc) as separate packages, because they are too slow and resource-hungry to be usable on Z. Also they take up no small space in the image, i guess?
-- App icons on cards?
Apps installed on my SD lost their icons in the paths. And the Menu Editor doesn't accept icons from external media.
So far my impression: indeed KDE3.5 is pretty heavy on Z, even though it is now installed to the internal memory. But I believe there are some ways to fine-tune it (e.g. further strip down things) to make it more usable and less demanding on Z.
By the way, is there anyone also trying/testing/using it here?
