This week they are talking about having multiple users being able to log into chrome at once. This is not the "sign-on as a different user" setting in Google Apps, but rather being able to have a second set of bookmarks, formdata, theme and more by signing in as a second user into chrome.
The potential looks great, but I found it a little confusing on the setup. Kids know how to text, so why not study too. I used a free texting app on my iPad, so I didn't even have to worry about a data plan.
