New user questions PB622

Hy to all, I'm new on this forum. Have just bought a PB 622 and after some days like it a lot (my first e-ink device). However I have some questions that I couldn't find yet:

Is it possible to get some custom programs to install as I would be happy to have an organizer linked to calendar?
Is it possible to install something similar to note-pad to take free notes, not only inside the books?

Thanks a lot.
