Did you look at the link posted? I’ve never seen a door handle like that, and I’m not even sure I would realize it was a lever if I saw it. It looks like a static part of the door to me.
I do agree that I’d probably end up pulling on it after some searching, but it wouldn’t be the first place I’d go.
You can do pretty much the same thing with Firefox: you sign in to Firefox to sync your passwords and browser settings, then (assuming you’re talking about Google calendar, Gmail, etc.) You can sign into your Google account with one click. That’s not really any less convenient.
Besides, I’ve hardly ever heard of anyone moving away from Firefox to Chrome, so I doubt the reason is any sort of convenience or design superiority. I’d attribute it to the fact that most people who already use the Internet (pretty much everyone) has already settled on a browser, with chrome-based browsers being the most common. So anyone new to the Internet will just choose the favorite as the default. This is especially true considering they most new Internet users are probably kids, so they’re not aware of concerns about privacy, monocultures, DRM, etc. that would drive someone to pick Firefox.
Basically, it’s not that Chrome is actually better than Firefox. I think it’s that the market is growing, and the most common browsers will grow more quickly than Firefox simply for the sake of familiarity.
