That's the thing, though - from HCI, we know that intermittent performance issues are actually worse than predictable performance issues.
That's interesting - I'm certainly not alone with this, though - I've seen others reporting the same thing.
Would be interested in hearing other peoples' experience, since it seems you and I are seeing just plain different behaviour. I'd say Siri activates correctly about two times in three.
Don't get me wrong. I'm not debating you or anything like that. You have legitimate gripes that a good deal of people are experiencing. Some of the issues may be improved by unpairing and then pairing the watch again to the iPhone. Hopefully, Apple will surprise us with another update later today. Anyway, thanks for chiming in...
