- When I bought this palm, I had no idea of what it was capable of. I bought it because I though it looked like a great device for a dayplanner. It turned out to be much more. I spent quite some time deciding on whether to get a WinCE device or a Palm. In the end, I chose the palm because of how thin it was (0.4 inches). This little device stores up to 10,000 addresses, 5 years of appointments, 3,000 to-do items, 3,000 memos, 400 e-mail messages, plus, there's plenty of room for extra add-on applications, books, language translators, image viewers, dictionaries, games, advanced calculators, and more.
