Microsoft Office Web Apps finally lets you edit your office docs online in a hassle-free way. I have always experienced frustration while using Google Docs as it messes up my formatting and I usually end up downloading it and editing it on the local machine. nOffice web apps solve that problem and has been such a boon. It has most of the basic features for editing excel sheets and powerpoint presentations and makes life a whole lot think this will lead to decrease in the usage of Google Docs which still has the advantage of being free but Office Web apps is whole lot better than its myself have shifted to the office web apps and haven't used google docs since then. Office has always been Microsoft's strong suit and this just takes it to a whole new level.
