I could really see Samsung doubling down and promoting the fact that their phones have a headphone jack.

I get that you are all aboard with the removal of it. For many people such a simple thing is really a fairly big deal. A true audiophile is going to want optical ports anyway.

The death of the floppy drive and optical drive weren't surprising. They both had limits, and flash memory prices are dropping as well. Plenty of people have become accustomed to the fact that the Macbook only has one port, but plenty of people have probably opted for something else.

Some people, like you, won't care or mind that it is gone. Others, like me, will just wait for the upgrade instead of doing the yearly one, or explore other options. There's other phones, and Apple is certainly gambling with this one.
