From the Kobo forums, it sounds like there's not actually much difference in tweakability. The stuff people do with the Kobos is quite impressive, and most (like KOReader which is my default) seems equally easy to install |

What is a TCR file?
eBook created in the TCR format, which was originally used by the older Psion Series 3 palmtop devices developed in the 1990s; stores the eBook text and formatting in a proprietary format used internally by the Psion device.
