Installing Calibre on EEEBuntu

I use often my EEEPC as E-Book reader especially when I travel by train. The program I use (FBReader) works fine and, in border-less mode with the page tilted of 90°, makes the EEPC an almost optimal E-Book reader. But since I'm looking for some extra features I decided to install Calibre.
Calibre is literally a all-in-one e-book software with many features from the library manager to external readers synchronization. I'm mainly interested in two features: Calibre library management and the RSS feed reader.
Installation
I simply executed Calibre installation command (all in the same line):

sudo python -c "import urllib2; exec urllib2.urlopen(

      'http://calibre.kovidgoyal.net/

      download_linux_binary_installer').read(); main()"
