Flash drives and remote access are two ways of making sure you have your data available wherever you happen to be. Online storage via hosting sites is another.
"div-Share" is one such site that seems to provide unlimited storage - though access to your files seems less controllable than might be ideal.
"X-drive" is another place where you can keep your files with some degree of security.
I would advise against using these for anything too personal but for many items they provide a useful alternative.
You can read more about online storage here at TechCrunch or via a search with Google.
