[Over]

• Amazon owns Mobipocket AND the Kindle. So it's in their interest to see the Kindle succeed. So why invest in long-term Mobipocket support for other devices, unless it is to ensure upselling to the Kindle from another ebook reader.
  
  Why is this bad?
  
  
• Mobipocket DRM is fiercely protected. It is somewhat of an open secret that Mobipocket DRM can be the only DRM mechanism used on a specific ebook reader.
  
  That sucks but... If it's the only secured format you'll really need, what's the problem?
  
  
• Mobipocket has shown little/no interest in supporting OS X. Boo!
  
  That sucks too. But... You can still drag and drop ebooks/music/pictures on the ereader.
  
  
• There seems to be near-fanatical insistence by people for ebook readers that support Mobipocket. (I'm personally not sure why this is the case - I own no Mobipocket books, have no issue finding stuff to read in alternative formats and have no desire to buy mobipocket books).
  
  Well, it's much more convenient to have few formats available. The more formats, the harder it will be to manage everything. And it hurts the ebook's availability: some titles will come out in Mobipocket only, others in eReader format, others in... Also, the Mobi ebooks, so far, offered me the best formatation.
