So, with the announcements yesterday of SMS client support in Hangouts (as well as animated GIFS and Location sharing) and the other new features announce for Google+ with the Video and Photo editing, I wonder how much it will help growth on the platform. Of course the iOS update had Google Voice support and maybe that will be baked in too. I use Hangouts a lot now to talk to family and groups that I'm part of and to automatically back up my photos and videos from my phone. It's really nice to be able to instantly go to my images from any computer and access the full size images without having to manually retrieve them. I will be interested to see how the SMS implementation is handled, but it could prove to be the "killer" feature to push Hangouts to more people. I like the fact that it works completely across all platforms. Whether I'm at my computer or my phone, or my niece's iPad or my brother's iPhone or even folks on crackberries or Windows, everyone can "Hangout" without the exclusivity of platform like iMessage or the limitations of BBM. I think the real key will be how fluid and responsive it is at full blown implementation.
