Why is everything branded with an 'i' these days? We don't know. But what the iTwin lacks in naming creativity, it more than makes up for in usefulness. Think of it as the remote desktop taken to another—waaaaayyy more simple—level.
iTwin allows you to transfer files easily and securely between two machines as if they were connected with a real-life cable. It's like having remote desktop access, but this is done completely with hardware!
Well, the iTwin does get help from your internet access, but none of your files are ever stored online. They just move seamlessly from one machine to the next.
Setup is a breeze (You can check out the video here, if you can stand to see Mac machines running the Windows OS). You just plug the two attached iTwin plugs into one machine, setup a folder for file transfer, and then plug one half of the iTwin into the next machine. Voila! Instant portal to your home desktop from work!
Expect the iTwin to launch in early 2010 for around $99.
