Yeah, I do mean it. Some of us have larger attention spans than others, but we've all got limits. I don't come to AppleInsider for snot jokes so it'd be OK with me if DED employed the "focus means saying no" philosophy.
DED's articles are kind of long. Can you show me specifically where this article talks about it "all done on the device"? I don't think you can, cause I don't think Apple or DED are claiming that. Apple is indexing a lot of information, but they're not connecting this indexed information to specific users.
I don't see where the article says there's a lot of learning done in your iPhone. I believe the learning is done by the app itself, plus Apple's servers, or the cloud. Then later, all this learning and fancy indexing is made usefully available to your device, be it tablet or phone.
If Apple repeats the 100 million number today, then it's a meaningful goal worthy of analysis and discussion. If Apple doesn't mention that number, then we should think of the number as a rumor with no connection to reality.
