Going to Cloud and Reducing Dependency on a Given Computer

[radderfire]

Hi Guys

I am interested in the concept of reducing my dependency on a given computer and moving most of what I do to the cloud. Things I need to do are word processing, using spreadsheets, web design, php coding, .net coding, storing photos, graphic design, photo editing, video editing.

Could I have any recommendations for moving to a cloud based setup. Of most interest to start with would be the word processing and spreadsheet recommendations. Continuity of service and reliability are important to me.

Thanks
