Today, I finally got iPhone3GS thanks to the cut of Internet cost of my house. It can make me use Internet everywhere with great touch panel interface, for examples, I can tweet in real time, and what is more, it seems to provide me new value, for instance, I can pack the real things in virtual world. My professor predicted this thing would enter the mainstream on his other blog. With having this progressive device as a start, I have to think about boundary between real and virtual, going back and forth through them.
