I'd be interested in learning how they implemented the UI - it looks like it's native to Windows 8 but runs just as well on Windows 7. Would be interested to hear what toolkit they used. So far, the UX has been impressive for a tool that has historically not run very well on Windows. Edit : They've mentioned the toolkits used at the bottom of the page. Apparently this is written in C#.
Are you serious? I ask this out of genuine ignorance, knowing only a little of what has gone on in the Windows world the last ~4 years. This is what Windows 8 apps are supposed to look like?
