Back in 2009, we might have been a little, well, acerbic in our reaction to the initial iTwin. Yet here we are in good ole 2013, and the plucky USB networking key is alive and well. In fact, it was CES when we saw its latest incarnation -- iTwin Connect -- arrive offering (somewhat more useful) private and public VPN services. At the time this was for Windows only, but that's now changed. Mac users can get the same remote desktop, file access and aforementioned VPN functionality, that will also work between machines of both creeds. If you're on the fence about that $199 price tag, remember that comes with access to iTwin's own public VPN servers, and no subscription fee.
