As I'm switching between desktop and laptop at home and office and university a lot:
1. What is the easiest way to save and open the same files across these different locations online without the use of any USB key or portable drive. I am referring to simple MS word documents, excel sheets, and other small size files no larger than 5 or 10 megs a piece. I want something that is quick and easy to access and uplaod to or download to
2. If possible to integrate within MS Word, Excel that would also be useful i.e. when opening a file, rather than browsing on a local drive, search an online drive.
