I'm not implying that Apple can't make mistakes - it's clear they can with Maps and Siri - but a) it would be extremely uncharitable to judge them on version 1.0 of Maps and Siri, both ridiculously complex features, and most importantly b) their overall product strategy is still the best in the business. Doesn't matter how much people kick and scream about the newest Apple mistake - does anyone even remember Antennagate? Tech people cling to these memories, but normal people forgive and forget.
1. In other contexts, the sheer perfection of their 1.0 products are exactly what Apple is judged so successful by. As with the commentary on the fingerprint scanner: the praise is that while other manufacturers deliver buggy, incomplete features, Apple gets things right on the first try.
2. While it's true that everyone makes mistakes, Siri and Maps were arguably the highest profile features on the 4S and the 5, respectively.
I also use for "what's the weather like today"
very convenient, give it a try, it's great
I think when parent(s) were remarking on execution mattering they were implying: 'Execution is key ... to the success of the feature (and consequently) the brand'. My experience is very few people know what Google Now is. Your preference of it does not demonstrate an example of that sort of success-due-to-execution that other posters are suggesting Apple's products exemplify.
I've even found myself thinking 'Siri, where's my phone?' when I can't locate it in my flat. Siri is addictive if you learn to use the tool.
I hope touch id proves to be successful, but I'm really interested to see what happens if it's not. How do you save face and stop investing in a technology, while also weaving a story that convinces customers they don't need it anymore?
