I registered just to say a few words in this thread although I'll posibly stay on the forum
To all of the ePub crusaders,
1) If Kindle doesn't meet your needs you have plenty of other devices to chose from. Don't want a reader that doesn't support ePub? Don't buy it. It's not obligatory to purchase a Kindle.
2) I don't see the need to introduce ePub in Amazon store. There are no problems in converting .mobi to .epub or the other way round. Those people who are not so into technology or simply don't give a damn about the file format are happy with what they get.
3) It's not true that popular formats are the best. Compare mp3 with flac. Book readers are for reading text for crying out loud! I do not need everything that epub is capable of. I just want to read text and I'm not interested in using a format because it's popular, trendy or advertised as "free and open".
4) Don't you dare call me a fanboy. I prefer a Samsung TV set to Sony TV set. I prefer Zen Vision:M to iPod. I prefer Pentax DSLR to Canon DSLR and I prefer Kindle to whatever else
All of the above devices were purchased after doing a lot of thinking and comparing. Don't make idiots out of those who don't think as you do.
Now take into consideration that people are happy with their Kindles and please - don't wage a war in the name of the "holly" ePub. If you want to worship it then do it in private.
Have a nice day.
