Free Online Storage

Now I'm sure there are many other services out there, but here is a quick list of free online storage, sorted by size.

Google Docs - - 1Gb
Google Picasa - - 1Gb
DropBox - - +2Gb - - 5Gb
Microsoft Live Mesh - - 5Gb
Google Mail - - +7.5Gb
Microsoft SkyDrive - - 25Gb
Google Storage for Developers - - 100Gb

Multiple accounts are possible with some of these services and something like Gladinet helps moving files into and out of this storage simple.

My personal favorite is still DropBox.
