Hi all -
First time poster, and about to be first-time ebook/Kindle2 owner as well.

I've been doing some research on supported book formats and found that I have some questions - I was hoping you might be able to help.
Short form, I'm a big believer in digital media... as long as I can use it on whatever device I want. I have no problem purchasing ebooks from Amazon for the Kindle, but I want to do my best to have the ability to read that book 20 years from now on whatever device makes the most sense. As such, MobiDeDRM *seems* to be a good answer. My questions are around the details - and likely fall out from my being a complete newbie here, so I apologize if these questions seem silly.
Question 1: What format does MobiDeDRM output a DRM-stripped Amazon mobipocket book format in? Is this a valid archive format I can keep (and read)? Or is it some sort of transitory format which I should translate into some other, readable format?
Question 2: If I need to translate the DRM-stripped ebook above into another format, what is recommended? I'm looking for best layout, portability, and no (or few) issues with tables, images, etc. Is it a .mobi? A .lit? etc.
The rule of three says I should have a last question, but honestly, I suspect getting the two above answered will get me a long way down the right path.
Thank you so much for any insight you might be able to share!
