Thanks for sharing those very informative and useful comments
It is not really clear to me why anybody will read Kindle forum if one is not going to buy new devices, but whatever...

Not interested in any unsolicited advices on what platform is better or why everybody should use Calibre (an excellent tool for what it was designed).
