Query: A Great Machine

The financial calculator motivated my choice of the HP Jornada 548. As a HP 12C user since 1978, I could not image buying a hand-help device without them.I wound up with much more.1. The color screen is is sharp and clear.2. Syncronizing the machine is easy. I have my Jornada synchronzied to my computer at work and home, making it easy to keep my contact and calendar on both machines up-to-date. I previously owned the 200LX whose motherboard failed. I, of course, did not have a backup plan, so I literally lost two years of my life. That will not be the problem with this machine.3. The reader is the greatest. I am now addicted to the world of e-books.Plan to buy a flash card. You can never have enough memory.I never thought I would say this, but here goes. I could not live without this machine.
