Since we last saw iTwin back in September, not much has changed -- two physically synced USB dongles create a AES-256 encrypted connection between two Windows machines for transferring files from anywhere in the world (provided both are connected to the internet, of course). We had a chance to see a controlled demonstration up close at CEATEC, and while it worked as well as expected it to, we're not quite sure the $99 price tag is low enough to pique our interests. We do appreciate the ability to "reverse" the flow of file sharing, but from what we gather it takes both parties to initiate the change -- clearly there's more flexibility in just setting up your own file server, but we're probably not the target audience here. If you're still interested but choose a lifestyle centered around a Mac, we were told an OS X firmware update would be available in early 2010, would apply to all existing models, and would allow both Mac-to-Mac and Mac-to-Windows transferring. Video after the break.
