Re: Extra battery?
If you travel a lot, it's a great perk. You don't have to roam the airport looking for an available power outlet. You don't have to worry about killing the battery on long flights or train rides. And if you're hanging out in the country with poor 3G/4G service, you don't have to worry about the phone draining the battery by constantly looking for service. If it runs low, just swap it out with a fresh one and go about your business.

And it's also nice if your phone crashes to the point where the only way to reboot it is via battery pull. I guess this isn't so much of a problem these days, but Captivate owners know all too well how important it is to be able to pull the battery.
