Apple Finishing Up Work on an Ultra-Thin 15" Mac Notebook

What’s most interesting here is that the 13-inch MacBook Air and the 15-inch MacBook Pro have the exact same resolution: 1440x900. This is why I had no problem replacing my Pro with an Air.

Does a 15-inch Air go closer to the 17-inch Pro’s 1920x1200 resolution? Or maybe it does 1680x1050? If so, why would anyone buy the 15-inch Pro? What about the 13-inch Pro? For the optical drive? Please.

To me, the 13-inch Air seems like the perfect size for my needs right now. But I would be tempted by a 15-inch if the battery life was even better. Right now the 13-inch Air gets 7 hours while the 11-inch gets 5. Could a 15-inch Air get 9 hours?

If so, what’s the weight trade-off? The 13-inch Air is just a sliver under 3 pounds currently. The 15-inch Pro is 5.6 pounds. The 13-inch Pro is 4.5 pounds. Could a 15-inch Air be 4 pounds?

Or. What about this:

What if a 15-inch Air replaces the 13-inch Pro in Apple’s line-up? Apple keeps the high-end 15-inch and 17-inch Pro for actual pros, but realizes the most others will be fine given how powerful the Air is now.

This would make Apple’s notebook offerings look like this:
