Summary: I needed to replace my PDA and wanted WiFi, Bluetooth, and GPS to go along with outlook, powerpoint, excel, and word. I did not want to pay monthly fees. The travel companion from HP, the RX5915, fit the bill. Other reviewers had complained about GPS satellite acquisition time, but I find it satisfactory without booster anetnnas. Getting WiFi to behave takes a little practice, but it will behave as the operator's skill improves.
