I might use audio cassettes if I want to record my own audio temporarily (and later copy it to a CD if I decide to keep it; I have done this before), especially if the higher quality of CDs is not needed. For most uses I would probably not use audio cassette tapes; I prefer to use CDs.
(One feature of audio cassettes is that it will stay where it was left off (even if it is removed and used in a different player), although this can be both an advantage and a disadvantage (for one thing, each cassette has only one position). At least, you can easily rewind it back to the beginning. There are other advantages and disadvantages as well)
