You're suppose to use a stylus for the PDA, but many people are getting too lazy to use one so they just use their fingers instead. Now, they're becoming more of a touchscreen where you do use your fingers. The new iPod (like the iPhone--but without the phone) is complete touch screen with your fingers. Same with the iPhone. Smartphones and PDA are now competing with each other, lol. However, there are still some things that the PDA will OWN against the Smartphones and that is performance.
