Wow, I'm astonished. I came across DropBox today, and if you don't already use it, I recommend you immediately kick yourself in the head and then download it.
Dropbox is a small application that sits on your computer, and upon install, creates a new directory for you called your DropBox. Anything that you put into this folder is automatically synced up over the web, and backed up on their servers. Any other computer that you use that also has Dropbox running will automatically (and almost instantly) sync up its own Dropbox with those same files.
Does this sound awesome yet? Let's use an example. You're at work, and you've just installed a little program that is extremely useful. With it you can write a script to automatically update your mail (or something similar). You know that you want to have the same thing when you get home, so you write yourself a todo item to remember to download this when you get home, and you also e-mail yourself the script that you wrote today. Now you've got to go home, remember to download the application, then remember to check your e-mail, and basically grab everything from a whole bunch of different places. And remember, this is just a simple operation.
Now the same scenario with Dropbox. You copy the .exe installer that you download at work, along with the script you wrote today, into your Dropbox directory. You get home, and turn on your computer. Its Dropbox syncs up, and you've got both files available. Done!
Dropbox is free, and allows you to sync up to 2GB worth of space.
If that sounds cool, there's one more thing Dropbox can do for you. In your Dropbox folder, you have a folder named "Public". Anything that you put into this folder can be right-clicked, and you can choose "Copy public link to clipboard". Once you've done this, you can just send any one of your friends this public link (it's in the clipboard now, so just hit Ctrl-V to paste it into your e-mail, IM, SMS text message, etc.), and they can click the link and download it, without even having to install Dropbox.
The only question I have is... Why didn't Google think of this?
Get it!
This is hot tech, thanks for the link! I suspect Google buy-out. This is too brilliant to let MS buy out (plus they have no business with cross-platform, they just kill it).
I think this is great.
IDEA: take a virtual machine and save it to your drop box. Now you've got your own PC you can access from anywhere.
That'd be sweet, although you'd still need to have a VM machine to run it. However, I've got Ubuntu running on my thumb drive, so that could almost do it.
A Virtual Machine would be a big beast to sync up, but with a delta, that would actually just be one big sync everytime you first pulled it down. Hmmmm...
