i own a HP ipaq as well.. friends were always saying, what do i need a PDA for.. until they saw what i played with it. with singapore going wireless now.. it's easy to logon the internet almost every place i go.. as i may not be lugging a laptop with me all the time. it's not BIG.. but it's good for a quick check. i can download maps and save on my SD card and it's particularly useful if i go travelling. must admit, the ringing tones volume, is very POOR! but i use it primarily for wifi (and playing games to kill time.. haha!), and it's Fantastic! sometimes, after my friends take pictures with their digital cameras, they'll pass me their SD card so i can save over for my to keep. instantly. it's easy. once you've had a PDA, you'd never want to go back to a normal mobile phone anymore. mine's bulky, but it has a relatively big screen.. so a little compromise here and there. now i love it.
I would agree on the feature-pack a PDA provide but I do differ the view that once you own it, you will not want to go back to normal phone ... I had a normal phone first, then PDA, then PDA phone, then back to normal phone ...
