The YO-520 has 1 MB of system memory, which is low for a handheld PDA but on the upper end for a $50 organizer. It also synchronizes data with your desktop PC, albeit through a slower serial port connection (though most of the data transfers you'll be doing won't be large enough to warrant a faster connection).
Close to the size of a PDA, this foldout organizer features only a 20-column-by-5-line screen, but does offer a bright backlight behind the display. Most of the space of the organizer is taken up by its myriad Chiclet-size keys--an entire keyboard and calculator are replicated on the unit. Additional buttons take you to the different applications built into the YO-520, including a calendar, scheduler, to-do list, expense calculator, and date reminder.
Programming the YO-520 isn't as easy as with your average PDA, where you click with the stylus until you find the settings. We found it was necessary to keep the manual handy, as we were constantly using secondary key functions to change the preferences.
In addition to synchronizing with data on your PC through the simple but thorough PIM (personal information management) software, the PC connection lets you download files from MyWizard.com and transfer them to your YO-520. These programs include sports schedules, college class notes, literature, and more. There is also a handy Info to Go feature at the MyWizard site to convert text from any Web site into a format readable on your YO-520.
While it won't be kicking the Palms out of dedicated PDA users' hands, Sharp's YO-520 provides more power and connectivity than your average organizer, and it would work well for users who need an inexpensive and portable PIM. --J. Curtis
