In the IT world there was a time when we all feared the Marco viruses that could be embedded into Word, Excel and other Microsoft Office Products. It was bad enough at one point that I found a single system with over 3,200 counts of an Excel Macro virus (it replicated itself quite nicely). Back then it was common for IT to recommend the use of RTF (Rich Text Format) instead of .DOC for documents and there was even an option inside exchange to force the use of this format even if the end user has Word as their email editor.
Microsoft is doing the hard sell on Windows 8 features and in particular they have made a valiant effort to push past some of the bad press (and consumer grumbling) about Metro UI and the way many of the apps are locked down. We have talked a little about this and even touched on it during some of our gaming coverage. Although you can launch “desktop” applications from the Start Screen (The Metro UI interface) you are not actually running them there. The only apps that will run in Metro UI Mode are ones that are downloaded from the Microsoft Store. This limits the functionality of the OS in many ways. Sure you can get some applications to interact with each other, but even then there are limitations.
