PDA is almost my main tool, additional brain. It is assistance to maintain connection with my primary contact database. It’s smallest and one of the most important devices for my work. With PDA I can access to any conversation I made with people, reshedule appoitment, connect to my primary system, write, send and receive email, attach to Wlan or UMTS network and use Skype. I miss UMTS radio, so I am looking to get Fujitsu-Siemens T830 or something similar. So far I tested many smartphones, but they are far behind PDA power and experience.
