I agree with many of the profile options already mention. However, the one profile feature I've REALLY wanted is a decent car profile. For this I would want fewer, but larger icons to show up on the display, just 2 in the dock (phone & iPod) and two rows of two at the top, enough for GPS, Slacker (or other audio app) and a couple of others. These would be "Car" profile pages that you could configure through the new interface that would only show when you are using that profile.
My goal is to minimize the amount of distraction while driving and be able to only see the things really needed while in the car and make them easy to hit while the phone is in it's car mount. In this mode I would also likely turn off Wi-Fi (not for power reasons but for notifications of hot spots it sees while driving that I don't mind any other time but are useless while driving), maybe different brightness settings or sleep/auto lock settings, Bluetooth on for car, but off when using normal profiles, etc.
The biggest problem with all of this is that it would benefit the customer only and doesn't bring more revenue to Apple, therefore it will likely never happen.
