Google's rush to improve its Google Documents cloud-based service continues. New capabilities are being rolled out on almost a weekly basis. An interesting recent add-on is the ability to perform OCR (optical character recognition) on images of text, or text from PDF documents and save it through the docs interface. The quality of the OCR is not fabulous (which is odd, as OCR is a very mature technology and desktop applications offer a high level of accuracy and formatting fidelity). Now that the slumbering giant Microsoft is beginning to offer serious cloud-based word processor services, Google will need to make sure its product is high quality.
