As we have seen information becoming more rich in content and the bandwidth of mobile devices increasing we have seen screen sizes increase to accommodate that richness, not a reduction in the information to fit smaller screens.
This is plainly untrue. Not only do we have the "Reader" mode that digests the information but we've lived in the RSS age for quite a while now. We haven't even started discussing the running of apps designed for the watch. We're well beyond WAP, as you've mentioned later in your post, and it's in a perfect place to create a browsing experience for something like the Apple Watch. Even Samsung has added a wheel to their lineup for the same purpose.
The Apple Watch requires you to carry your iPhone for internet access! Which means in this case you do have the better experience with you right in your pocket!
I bolded the operative part of your statement. To answer an earlier comment you made: Plenty of people made the case that cell phones were a terrible form factor for browsing the net.
Even though that requirement didn't exist for cell phone cameras they still didn't outpace traditional point-and-shoot cameras until their quality was close to parity, we all know this already.
Outpacing anything is not a factor in this conversation. Nobody's telling you to throw your phone away.
Where did I assume your motives? I didn't suggest any motivation whatsoever, in fact I asked what your motives were.
You said I was evangelizing the watch. Your question was built from that premise. Browsing on the watch could turn out to be totally useless. Nothing I've said actually discounts that possibility because I'm saying, instead, that you can't tell that from here. I can invent reasons, but that's incongruous to the point I've been making.
And they have also told us that those assumptions can be right, so the question to you is: why do you believe these assumptions to be wrong?
I don't believe they're wrong, I just don't believe they're right. Now if you're really asking why I'm receptive to the idea it's because I have a Pebble Watch that, in short, is a second monitor for my phone. I have plenty of cases where it's more useful to get information on that display than to remove my phone from my pocket. If you'd like to know more about that I'd be happy to share that info with you.
And I can pose the irrefutable counter-argument that there is no reason to think it will happen...
Lots of people thought that their reasoning for cell phones not having cameras was irrefutable, too. It's not. Just being proven wrong due to lack of foresight is reason enough. The real irrefutable question is: "Do modern smartwatches want to part you from your money?" I'm not being snarky, that's perfectly fine.
So again, what is the advantage that will attract users? Why would somebody use the browser on the watch instead of the browser of the smartphone in their pocket?
You can reach your wrist quicker than dig into your pocket. I get headlines on my Pebble Watch, for example. I'd love to be able to scroll down and finish the story since I'm already there.
