Nothing too special required
I create/keep all my notes in TuxCards - simply export them to HTML
Then import into Calibre and convert to EPUB - Gets you table of contents etc
The 1st thing I put on my Kobo Touch was 2MB of personal notes
and music 100 + songs with lyrics & guitar chord diagrams (also from TuxCards)
Books were my 2nd priority. LOL
