Thanks, Sameer - If I understand it properly, a chart would be like this:
- Kepub from Kobo store
- eReader: yes
- phone app: yes
- desktop app: yes
- Clean epub from anywhere
- eReader: yes
- phone app: yes
- desktop app: coming
- ADE epub from some store
- eReader: yes
- phone apps: maybe
- desktop apps: maybe
Is this right as of 31 Dec 2010?
Oh, one other point: Most of the books in the Kobo store are available as Kepub
and as ADE epub, although I'm not sure of the percentages.
