PROs:=====1. Adapters have backward compatibility to previous HP iPaq's. I can now use my previous iPaq that did not have a power source.2. Uses Windows Mobile (although version 5 not 6). It is able to handle my Microsoft Exchange emails with no problems, as well as share tasks and calendars that's on my Exchange server.3. Has the following main features - GSM/GPRS/EDGE/Bluetooth/GPS/802.11b Wi-fi. WiFi really helps me out at home or at hot spots if I want to do a quick check up on the news without having to go to my computer.4. Having the QWERTY keyboard and capable business functionality has made my life easier. I'm able to do my work emails while I'm away from the office.CONS (minor):=============1. GPS photo tagging is quirky (often times does not work, no fix).2. Help files sometimes does not have the right paths or software.3. VPN is hard to setup -- this is not an hp problem but a Windows one.
