the way Apple's latest MacBook Pros
switch between their integrated Intel graphics and the NVIDIA-sourced, power-sapping discrete silicon pretty much since day one (we're sorry, but Tweetie just doesn't need all the horsepower our systems have to offer). Apple has yet to pony up an official solution, but a neat little utility -- Cody Krieger's gfxCardStatus -- has been quietly evolving over the past few weeks into a decent substitute. Originally designed simply to let you know which chipset's currently in use, the latest version, 1.6.1, now allows you to toggle amongst them by hand. It's said to still be a little bit on the buggy side, but we're delighted (and not really surprised) to see that the community came to the rescue in short order when Cupertino didn't.
