I just noticed a new link when checking my hotmail this morning, to "Windows SkyDrive". Microsoft are offering 5GB worth of free online storage. It works with Windows or Mac with Firefox or Internet Explorer.
There are personal, shared and world folder options. File transfers are SSL-protected. What I found particularly interesting is that you can use the shared folders to colloborate with colleagues and set permissions for each person on a folder level. Nice angle :-)
I'm getting tired of emailing stuff between work and home. I'm also tired of getting down under my desk fumbling with a flash stick, so I think I'll give this a test drive for a while.
You can learn more here.
