Gmail: Storage Concept

Anybody using Gmail can agree that with almost 7.5 GB of storage (as of 8/28/09) and growing, they never have to worry about running out of space. In fact, I only use 3% of that space after 3 years of using Gmail. Most of them would also agree that it can be complicated keeping track of an old file they received in an email. They want universal access to it across any computer or mobile device, anywhere in the world. So how can they do that? Well, at the moment they can download the file to their laptop, desktop computer, and phone. And email it to themselves after making changes, then re-downloading it to the other devices, overwriting the old file. Now we come back to those extra GBs sitting on the Google sever just waiting to be used. I think that there should be a way to upload your files, and organize them in a simple file structure, just like you would on you computer. Unlike on your computer however, files could easily be emailed with a click. They could be transferred here from an email with a click, and easily uploaded from your computer. Also unlike the desktop of your computer, they can be accessed from anywhere in the world, and on any device. This would be a great use of your extra Gmail storage space, andif you run out, you can easily upgrade your space with a "Google Shared Storage Plan."
