What about Office 365? Skydrive? You know Microsoft has Word, Excel, and all synced with Skydrive now. There are web based versions of Office that Microsoft created. I can sync a folder on my hard drive with my Skydrive, just like Dropbox and Google Drive. I can also open word documents inside of Skydrive. I see Word, Excel, Powerpoint, Onenote, and Excel Surveys as possible options for files i can create inside of Skydrive. Give it a try. It sounds like you didnt know it was there.
