I have one of the pilot Chromebooks they were sending out for free a year or so ago. It's not just Google+, it's nearly any of the cool things you'd want to do online. Watching any kind of video is unbearably laggy. Heavy sites like (new) Twitter or (as mentioned) Google+ are completely unusable due to scrolling/typing lag. I get the "release early" mantra but I use my Chromebook for light browsing only. It can't possibly replace a real notebook.
