I purchased the RZ1715 about six months ago, and it has already worn out---battery will not take a charge, before that it became unpredictable in its behavior, with a lot of soft reboots. In contrast, my previous PDA---a Toshiba that was awesome---lasted about a year. My first PDA---an inexpensive Palm, purchased simply to see if I would use a PDA---lasted two years. The RZ1715 is so radically limited on memory that "Out of Memory" errors were a daily occurrence; I had 64MB expansion card in it, but it only recognized the card about half of the time. This PDA is simply not built to last.Thankfully, I purchased a replacement plan when I bought it---now I'm only hoping that they replace it with something better. Wait for the sale and spend the extra $75.00 on something with enough memory to do what you want it to do.
