So how would you propose to say it? Dropcaps don't work in old-MOBI? MOBI7? MOBI The First? Regardless of the file's extension and the semantics involved, we still need a way talk about it and express the differences.
To me, it makes perfect sense to to say that dropcaps don't work in MOBI, but they do
work in KF8. It's a heckuva lot simpler than saying dropcaps won't work in the format formerly known as MOBI (the fallback format reserved for older kindle devices—and even some of the newer ones whose firmware is less than X.XX), but will work in newer MOBIs utilized by Kindles Fires (and eInk devices with firmware greater than or equal to X.XX).
Don't get overly attached to the file's extension. There's just as many old-school Kindle eBook publishers who are accustomed to thinking in terms of uploading and downloading PRCs. Times change. There's some confusing stuff going on under the hood of MOBI right now and I think the terms MOBI, KF8 and Combined (or Hybrid) MOBI/KF8 are quite helpful, actually, in determining what someone may be trying to say/accomplish. It's important for people to realize they're creating two different
(as well as separate and distinct) versions of their ebook when using Amazon's official creation process—regardless of the fact that the final product you upload happens to be a single file with the .mobi extension.
