What's the best feature on the iPhone 4?

So, we've all probably heard of the iPhone 4 by now. What's the best feature on this new smartphone? The front-facing camera and the ability to video conference? The high-resolution retina display? The super-slim design? The ability to multi-task? The built-in gyroscope that will allow games to leverage six axes? The LED camera flash? The A4 processor?

For me, I'd have to say that it's probably the built-in gyroscope. I don't play too many games on my smartphone or iPod touch, but the ability to leverage a gyroscope will allow game developers to create mobile games that will be similar to the Nintendo Wii. Imagine carrying the Wii in your pocket. Now, stop imagining and get an iPhone 4. I think we'll see some truly innovative games soon.

If you use your iPhone as a GPS navigator, then you'll be glad to know that the GPS can navigate in the background while you perform other tasks. Just make sure you're not multi-tasking while you're driving.
