It's no secret that I'm a big fan of Siri, Apple's intelligent assistant. While Siri hasn't yet become as smart or as useful as 2001: A Space Odyssey's HAL 9000 (which might be a good thing), Apple has quietly added some new features to Siri in iOS 7 that turn it from a useful but sometimes frustrating beta app to a really helpful assistant.
Siri's new interface fits into iOS 7 better than the previous incarnation did in iOS 6. It literally fades into view on top of whatever you're looking at when you invoke Siri. You'll find that Siri answers your questions faster and usually more accurately.
Apple also has Siri check more sources than ever before, such as Bing, Wikipedia, and Twitter. That means that not only do you get more answers,
