I'm using O2 XDA IIi to:-

- keep clients contact
- keep track of my busy schedule, I've lots of press conferences, events and product launches to attend
- note is extremely important to me as I can use it to jot down important points to remember, it is very useful especially during product launches in pubs, sometimes too dark cannot see anything properly, so PDA's backlight is perfect in this condition

But one bad thing about my PDA is the ring volume is too soft, can't even hear a thing in noisy places. Thus, I've to use bluetooth to solve this problem.
