Looks very interesting!
A couple of comments/questions:
- Can you give us more details about the software? What apps are included? What functionality is included at release, and can you tell us anything about future plans? How often do you intend to release upgrades?
- Is your cloud service the only means to transfer documents? Would I be able to continue to use the Remarkable even if the cloud service would shut down? For example via USB, Google Drive, Dropbox, etc?
- I miss backlight, à la Kindle Paperwhite.
