Don't get me wrong, I love my Watch, but in no way does it even come close to replacing my phone. There's zero web browsing capability (even if there was, how awful would that be?), replying to text messages is a pain, most of the apps that people use daily are a total no-go. What it does, it does very well, but you can't expect a 42mm screen to be a competent replacement for a phone.
That's a good point. It'd never be good for web browsing, or reading, or... a lot of things.
What I was thinking was that maybe they eventually have it where maybe you can make phone calls right on it, do siri things and all of the other stuff the Apple Watch can do at present. Then push everyone to iPad or iPad-like devices for the browsable stuff.
