You must mean the very few million folks who own an original SE, and at that you'd be severely understating the case. Well anyway now you sorta know someone who still owns two of the original ones.
Yeah, some of us do just prefer a smaller phone. So, Apple's been smart enough to keep one in the lineup. I only wish the SE 2 retained the exact external dimensions of the original!
I don't know if there were any official Apple commercials for the original SE (there are some fan-made fake ones though, mostly based on stills taken off the keynote) but the keynote itself in March certainly featured it... starting at around the 30min mark.
