"This is exactly why so many of my friends and family use Hangouts née Gmail Chat. We can use it in the browser at work just by keeping Gmail open in a tab. No IM applications to install or concerns about whether we're running Windows, OSX, or whatever." That's exactly why I don't use browser-only IM clients. I don't want to keep open a full-fledged browser only to stay online when something much less would be sufficient. Ideally, a IM should offer a broad list of solutions: web-based, desktop native clients, mobile apps, and whatever else one might think about. One size fits all is only a sure way to self limit the adoption of your IM solution.
