I'm sitting here, right now, sending myself 7M of files on my Gmail account. Why? I left my thumbdrive at the office, I need to quickly port some files around, and I've got plenty of space available to do it. And it's got me thinking.
Sure, there are hacks out there to let you use your Gmail as a mounted disk in Windows, but they still have to save the files as email messages with attachments, and that's still a pain. Google needs to go ahead and start up some kind of Gdisk, letting you stash files online. Web interface, integration into Google Desktop and maybe a context menu option for Windows, and Samba/DAV support so you can mount it under Windows or Linux as a drive and use it that way. Give users direct access to their Google Docs & Spreadsheets, Picasa Web Albums, and Gmail attachments in subfolders. And, last but certainly not least, give each Google account a certain amount of space, and share that space between Gmail, D&S, and Picasa Web. It seems like that should be a relatively simple undertaking to me, but maybe I'm missing something.
