Live Traffic Videos Coming To Your Mobile

Over in Taiwan, they're introducing a new service to let you check up on traffic via your mobile phones. You'll be able to get streaming video of real-time traffic conditions at 42 major congestion spots. It will be interesting to see if this catches on. My first question is how clearly you'll be able to see what's going on via the mobile phone screen - though, as resolutions get better, I imagine it will be perfectly viewable. Second, though, is how many people will use this offering, as opposed to simply checking the traffic on the web via a PC before they leave home or the office? What's the advantage to having this information be mobile? Certainly, it will be useful in some cases - but it would seem to be much more valuable at a PC.
