Forget about checking the weather, everywhere I have used the AW to pay for things, I ALWAYS gets "That is so cool" or "I want one" responses.The 'smartwatches are useless' crowd is neck and neck with the 'check out this trivial item I did with my AW, it's so totally worth it' crowd.
The AW can be very useful in many ways but the majority of people have not owned a smart watch yet so they are having a hard time justifying it.
This all reminds me so much of when the iPad came out. Comments like "It's just a big iPhone" were hilarious.
