I went to Sheung Wan today to buy refills for my Fisher Space Pen. Traversing to this part of the Hong Kong island is unchartered territory for a guy who spend 99.9% of the time on the Kowloon side. But since I have the address of this particular shop, and with my trusty iPhone 3G in hand, I should have no trouble finding it. It's almost true, since GPS and Maps on my iPhone gives an accurate proximity as to where I am and where I want to go. However, if you're clueless as to directions as I am, even finding a shop that is supposedly 3 minutes by foot from the MTR station can turn into almost a half hour walk. I kept walking to a different direction from where the map was pointing. I had to walk all 4 directions to see which one was the right path, and that's a lot of wasted energy. The built-in compass on the iPhone 3G S will not only show the proximity, but where I am standing and which direction I am facing. That's sorely missed in my iPhone 3G. I think this feature alone is worth upgrading to 3G S for me.
