Discovered this cool thing with Windows Live mail it has build in office 2010...A cool feature to possess to make quick word documents,presentations and excel sheets..
Plus its easy and doesn't involve much of work..Documents from our computer can also be uploaded and saved online..
A certain disadvantage is the fact at a time we can upload only upto 50mb of file size what can you expect from a built in office... Its way better than google docs where the document starts to hang when file size is large
Its possible to print as well , this alternative may provide an efficient way of storing your data and files online
OpenOffice is also a great way to get rid of the large size problems with microsoft office and can be downloaded free of cost from the site
