Have you recently had the need to save a large file ( up to 2GB free!) in order to share it with others or to have it somewhere where you can access it on multiple machines including your smart phone?If so why not give Dropbox a try, it even has an iPhone and Android app making you truly mobile. Other storage spaces such as Box.net offer 1GB but with crucially a 25MB file size limitation, whereas Dropbox offers unlimited upload up to your 2GB limit - check out the features here

Many thanks to @willfinch for the heads up on Dropbox.com
