I have been broadcasting live video using my iPhone 4. I've been waiting to see if the new iPhone would be worth upgrading to. Now that the iPhone 4S has been released, I can tell you that there have been specific improvements to the camera and video processing:
• 8 megapixels, up from 5
• Wider aperture
• Additional lens (5 instead of 4)
• Faster shutter
• Face detection
• Faster processor
• 1080p HD video
• Video stabilization
• Temporal noise reduction
Hopefully some of those will result in better video broadcasts, with better color, sharper images, less graininess at night, less shakiness and less problems. The download speed is potentially doubled, depending on the network, but the upload speed is unchanged, so that will be of little help.
Another benefit is the integrated Siri voice assistant, which will apparently allow me to do more hands-free while driving, such as getting addresses and directions, sending texts, etc. I'll have to wait to see it in action.
Will it be worth $200 plus $55 tax to upgrade? I guess I'll find out in a week, because I've already ordered one! My wife should be grateful to get my iPhone 4.
It's a shame that Steve Jobs had to pass the day after it came out. This is his legacy.
