Apple took away the internal floppy drive but kept USB ports around so people could plug in things like external floppy drives. No such option exists for FW. By "started ditching" CD/DVD I assume you mean the Air since the rest of the computers do have optical drives. You can buy an optical drive for the Air and/or 'hijack' another computers optical drive. No such option exists for FW. They are currently holding off on Blu-ray but you've been able to burn a less-than-fully-functioning HD-DVD for years and, for a time, Apple even touted DVD SP as being first to market w/desktop HD burning.Apple ditched Floppies long before everyone else and everyone screamed. They were right. They have starting ditching CD/DVD drives in favour of wifi and download, and I think that fairly soon, they'll be proved right. They held off on the old HD-DVD/Blu-ray thing because they hate to be wrong.
Of course this all ignores the fact that every Mac made in the past decade or so, even the newly Macs, have FW w/the exception of the new MBs. I don't see that as a sign of Apple migrating away from FW. I see it as a sign of Apple removing a desirable feature to help separate to increasingly similar product lines.
