This is my third in the Palm line. I keep upgrading. I would truely be lost without my Palm Tungsten. It keeps my calendar. I have hundreds & hundreds of contacts. It keeps them all organized into easy categories that I select, or make up. It stores information about the person's home AND business info. My Tungsten has a built-in MP3 player. There is no need for me to carry extra electronics, this one does it all. I can download family photos and video clips. I can download full-length television episodes, or whole movies! And the SD Slot makes it so easy to use my Tungsten for not only business, but for entertainment as well. I would not be without mine!
