But as a Palm software app developer, I have many models such as m100, IIIc, Vx, Zire 71 and a T2. All sync fine with the PC and the data survives. Just one step is needed. When you sync a new unit, select the name that has the data.

If you move to the Axim, it's quite a different beast and moving your Palm data is not so easy. I will not discuss it but Dell will. Call them about how they help you move over.
