Google+ Hangouts is one of the best free group video chat apps we've ever seen, and now the collaborative, multi-person video calling is coming to all Gmail users.
In addition to chatting with up to 9 people at once, with Hangouts you can collaborate on Google documents, share your screen, and watch YouTube videos together. It's a full-featured web conferencing solution—now directly accessed in Gmail (it'll replace the previous video chat and is rolling out today and over the next few weeks).
One of the best features is you can reach others from Hangouts now whether they're using Gmail or are on Google+ in their browser or mobile phone.
