Query: Palm PDA

I am extremely happy with my Palm PDA that I purchased through Amazon. I was unable to buy it in a retail store because it has been discontinued but wanted to replace my previous model. Amazon was the only place that I was able to find the exact PDA that I wanted. The seller was reasonably priced and prompt. They also followed up with me to make sure I was happy with the product.
