Anoying "save as a copy" process that was never asked for and takes longer to save a file

Is there a particular reason that Adobe have changed the simple "save as" so that we now need to to hit a "save a copy" button each and every time we  save out a file as a jpeg or different format? Other softwares seems to present a time honoured save as dialogue that gets the job done. Adobe for some reason have had to inject extra steps in to something very basic. They could have spent the time in to actually developing their software offering Linux support and improving 32bit support but noooooo they screwed up the save as option.....Money well spent Adobe.....
