Agree. I was so excited to see this announcement and kept reading and reading to see if they had left the headphone jack :( I would have bought two _today_ if they'd kept the same outside and just updated camera + internals.
As it stands, not sure what I'll do as an updated SE was my last hope that Apple would continue making a phone with a headphone jack, but that was probably a pipe dream to begin with.
And please don't try to sell me on Bluetooth. It works OK 60-70% of the time in my experience, but it's super frustrating when it fails (esp. when trying to help older less tech-savvy relatives) and I often find myself just wanting to be able to plug in a darn cord. Ahh the good 'ol days...
