Are you using Dropbox?
Dropbox is the easiest way to store, sync, and, share files online. There’s no complicated interface to learn. Dropbox works seamlessly with your operating system and automatically makes sure your files are up-to-date. Available for Windows, Mac, and Linux.
The more I use Dropbox the more useful I find it.
For me what makes Dropbox work for me is the integration with OSX and syncing across multiple machines, and I can access it through a web browser at work.
If I was a Windows user, then Skydrive would probably be a similar alternative, though of course Dropbox does work on Windows. Skydrive does have 25GB of storage compared to Dropbox’s 2GB. But for $10 a month I can upgrade Dropbox to 50GB, which is a fair bit of online storage.
Another way of thinking about Dropbox is as an USB stick that doesn’t require removing, ejecting or holding onto, so difficult to lose your Dropbox, unlike an USB stick.
So what about losing the cloud? Well you never know one day Dropbox may stop working, other web services and tools have done so, but until then it works.
