PR mistake
Siri was, and still is, "Beta." So if it doesn't work, no big deal. But frankly, it's worked about 90% of the time for me. Sometimes iCloud seems to be balky, and there's a server that's not getting you. Sometimes you slur your words or ask a question in a blast furnace.
The Maps app should have been given the same status, while not taking away the old version with Google Maps until they could fly on their own.
Apple's not great about networking yet, because I think it was a blind spot for Steve. He didn't know who to beg and bully and seduce into doing it exactly right. So he left it to others. And fired them if they got it wrong.
I think they'll learn though, and I agree with their corporate decision on this one: but they could have eased it in for a year while they get something for Street View.
It is apparently pretty atrocious in places like Boston and London, most of Europe in fact. It's great in China. So the loudest complaints are from the Europeans. In parts of the US, like San Francisco, it's working fine. It's been pretty cool for me in L.A., though maybe it's just my neighborhood near the studios. The mistakes that are surfacing (through crowdsourcing, much better than any internal testing) are more important than ever, because of the very fastest rollout in the most countries that Apple is trying for their single model that works almost everywhere.
So a lot of times, I'll try out Apple Maps a few times, unless I get lost. If I do that, I'll go to the numerous programs in the App Store, or wait for Google while I use their maps on the Web.
