If you follow my blog, you know I've been using Windows Live SkyDrive to host my files and presentations for public download. It used to be cool that it gave you 1GB of free space for you stuff, but now it's flat out great that you get 5GB!
There are now 38 supported countries/regions. Check the team post for details.
It's free to use, and you can create private, friend-shared, and public directories, so I'd definitely recommend you take a look.
