Note that switching between GPUs doesn't require a reboot, but you do have to log out and back into your user account, closing apps in the process.
With the 9600M GPU turned on, we got 4 hours and 14 minutes on our video-playback battery-drain test, which is very impressive for a desktop replacement. Switching the 9600M off added about 30 minutes.
We've heard concerns about the sealed battery compartment, which means you can neither replace a worn-out battery nor use an extra battery on a long trip. Over 4 hours of use with a 17-inch laptop should help assuage the extra-battery concerns, since that's more than double the battery life of most desktop replacements.
The lack of a user-replaceable battery is a more serious issue. Apple claims that the battery in the 17-inch Pro is good for 1,000 recharge cycles. If accurate, that means the battery should outlive the useful life of the laptop. Apple's retail stores will also open the chassis and replace the battery for a fee.

Conclusion
The redesigned 17-inch Apple MacBook Pro is an expensive machine but its excellent performance, impressive battery life and attractive, solid design make it an appealing proposition.
