Though more prevalent before, the stand-alone PDA has become increasingly rare. It's become integrated into the cell phone for those of us who choose to use it (I don't; the all-in-one cell phone is a hassle. I tried using it as a music player, but that was a mistake. Thankfully, I didn't rely on it to keep track of my appointments. I'm only going to get a cell phone for dialing in and out from now on).
