Another argument for the iPod Touch
Lifehacker has yet another take on how people can use an iPod Touch as a replacement for the iPhone.
Their post goes even farther, by adding a Mi-F hotspot to give your Touch complete mobility.
I can't imagine that the battery for the Mi-Fi or the Touch would last a full day. However, my neighbor did just pick up a new 64GB Touch and says the battery life is much improved in the newer model.
