I have been screwing around after my post 2 years ago, working with quite a few different companies and industries! I believe when I wrote that post, never realize that i can be in Singapore as now. Ok, enough for the nostalgia.
Currently I see that major change will comes to mobile services. There are few areas have been developed restlessly such as location based, augmented reality, mobile online store, mobile social network etc, etc. Anyway, I going to get android phone by next week, and see what could be done with that. Idea of letting the demand exposed to supply and vice versa seems to be still relevant. Mobile will lets it happen everywhere, and anytime, even realtime! But it could be long term purpose.
At the moment, integration between mobile and cloud computing looks promising and able to deliver totally new experience. A big world in a small device at our hand!
