Fortunately, Ars Technica was there to put some of my fears to bed, putting the Pre up for battle against the iPhone as the ultimate travel companion. Thankfully for me, the iPhone ends up as the clear winner. The article notes the wide availability of iPhone charging accessories if you happen to be short on battery with your charger stashed away in your checked baggage, as well as the huge number of apps available in the App Store to aid in your travel or supply time-wasting entertainment for long layovers or flights. It also notes the iPhone's battery-saving options (like Airplane Mode, turning off WiFi/Bluetooth, screen brightness, etc.) as extremely valuable when you're traveling and don't have immediate access to a charger.
What are your tips for traveling with your iPhone?
