As part of today's announcement that a new Chromebook and Chromebox are on the way, Ars Technica is also reporting that offline editing is finally coming to Google Docs in June. We don't have a lot of details right now, only that it will sync any changes you make as soon as you get an internet connection, and it will only work in Chrome (at least to begin with). We'll have a full rundown of the addition when it finally gets released, but for now, keep your eyes peeled for updates over the next few weeks. [Ars Technica]
