The mobile Google Drive app just keeps getting better and better. Are we ready to ditch the desktop web app for its iOS and Android package? Hardly, but with ever decimal point upgrade the disparity between the two keeps getting smaller. The latest round of updates finally delivers document editing to your iPad and iPhone, including the ability to format text and see live changes made by your collaborators. You can also now view presentations, including speaker notes. The Android version also got a few nice tweaks today, most notable being the ability to see and reply to comments on docs. Google is also promising that real-time updates will be coming to spreadsheets very soon -- which should excite on-the-go number crunchers. Check out the video after the break.
