Apple certainly knows how to generate buzz. They introduce two new telephones, and the internet lights up.

Today’s big news is the new iPhone 5s, a more powerful computer in the same small-sized box. The chip is now an A7, far more sophisticated, and faster. Why should you care? If you play games on the phone, serious games with adventurous graphics, you will see more detail, more fluid movement, and the kind of sophistication you’re accustomed to seeing on, say, an iMac. If you’re an avid iPhone photographer, you’ll find that autofocus is quicker, and that frame rates for video are faster. Of course, the overall operation of the phone-as-computer is snappier, more efficient, more energy efficient, too. There’s a sexy fingerprint sensor, too. And there’s a more natural flash.

Both phones now include an 8MB camera.

The 5c is designed for fun–it really is a cool-looking phone. It costs about $100 less than the 5c, and it comes in five colors. Aside from the processor (here, it’s an A6, which is still quite powerful), and the lack of a fingerprint sensor (some people will need one, some won’t), it’s very similar to the more expensive model.

For those whose iPhone 4 was beginning to look and feel a bit old, it’s now time to refresh the phone with a new one. For those with an iPhone 5, it may be wise to wait because there’s nothing here–aside from gaming speed and a better camera–that would compel a shift. Nice to have, not essential.

Apple has succeed with their iPad cases, so they’ve picked up the concept here, too. You can buy a nifty plastic case, in colors, for the 5s, or nice leather cases for the 5c.

So that’s the quick scoop. I’m sure you’ll see another hundred articles about the phones by morning, but I was curious for myself, and thought I’d share my notes with you.
