Before you start getting the credit card out, consider my advice: This would not make a good handheld device for a genealogist.
Why? It has 32MB of memory, and it’s actually more like 20MB of memory. That’s not enough memory to store the applications and data you need as a genealogist these days. It doesn’t have any kind of flash memory card expansion. Its screen is also 160×160 – that was great a few years ago, but with some Palm genealogy applications supporting a higher-resolution, you might as well try to get a Palm that takes advantage of it.
