For what it's worth, I dislike these MiFi gadgets. I understand the benefit, but it's also yet another battery powered doodad to carry around. I want to carry exactly one battery-powered gizmo on me at any given time.

I suppose that means I could jailbreak my iPhone, but the iPhone is "good enough" that I rarely feel the need. Still it gnaws at me when I just want to do something quick from my laptop and I have to pony up for some hotel wireless monstrosity.
