Yeah I just use the double tap button more now, "hey Siri" is not quite right yet, (hopefully a software update will fix it a bit.) It's not a big deal, but I also would love to hear her voice come from the watch, but my guess is that would only happen with Gen 2 or 3.
Either way I'm happy with it. I just hope I never drop a 7 pound iron pan on the screen, (that cnet torture test made me kind of wish I ordered the Sapphire Screen SS one, lol)
