I noticed last night that Google has anounced a load of new features for Docs users. Biggest one is probably the fact you can now upload any file, and Google Docs will act as an online harddrive. Though currently there is only a gig of storage space.
There are also features like docx and xlsx support, improved drawing tools and lots of fancy spreadsheet functionality.
I would say it all looks pretty exciting, it seems there is a enough functionality for me to try and get us to use Google Docs more at Oomph.
