During my travel I walked - took a bus - took a train and last took an auto. My experience with the N95 GPS fix quality in buses and trains has not been so good, so this time I used the N78. As can be seen on the map, I lost the fix just a couple of times. I took care that I was standing near the door or window of the bus/train. All the while the app constantly kept updating the speed, map plotting, latitude/longitude and all the graphs pretty accurate. A day earlier when I tried out the app I was amazed to see that it even counted the steps I took accurately. Although I could have uploaded my track once I reached office I choose to show it live so that my friends can track me in real-time. Any photos taken along can be uploaded and as they contain location info they can be seen along the track exactly where I took them, applies even to videos taken.
So at the end of my travel all I did was log on to http://sportstracker.nokia.com and saw my entire route. To put the pics I'd taken during my travel just hit 'Upload to service'. Simply amazing. A travel recorded and that too with pics I took. Vaibhav rightly mentions that this app is just not for the sports junkies, anyone can use it, atleast I'll take care that I take my N78 along for every outing of mine ;)
Here's the link to my track. Click on the pics I've taken to see description. Even updated my sidebar to show a widget of my track. Get your own widget from here.
