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 - http://goo.gl/vXYmQ - 1Gb
Google Picasa - http://goo.gl/GzPa1 - 1Gb
DropBox - http://db.tt/AbGHhNR - +2Gb
Box.net - http://goo.gl/Ls4dy - 5Gb
Microsoft Live Mesh - http://goo.gl/iDtc6 - 5Gb
Google Mail - http://goo.gl/CW9hv - +7.5Gb
Microsoft SkyDrive - http://goo.gl/gkzAD - 25Gb
Google Storage for Developers - http://goo.gl/1hhsZ - 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.
