Yes, if the year was 1995, this would look awesome. But, it's 2012 and I saw the word portable to make it even more horrendous. I'm surprised it wasn't written in Java to put yet another nail into its coffin. Yawn... Move on to the next Channel 9 video...
I second the "Who cares about yet another language that will never gain popularity?" sentiment. As far as programming languages go, if it isn't a Channel 9 episode about C++, C# or VB, in the worst case, it just isn't worth watching. Why? Because, the practical present and future applications in business of these "revalutionary" languages are exactly 0. Noone will ever adopt yet another programming language in this day and age, unless it is radically different and really has a top notch class library to boot. This is the only reason that Java and its derivative, as much as I hate to call it that, C#, made it into the real world.
Looks good, except for the ugly retro color scheme which just has to go. Apparently there are three ways to do GUI at Microsoft, two of which are hidious, IMHO:
1) Way too light - Live Mail - everything is white, light blue, or some indistinguishable permutation of the two
2) Just right - Visual Studio 2010 - things have just the right amount of color and contrast
3) Dark, bland and dead - Visual Studio 2012 - welcome to the dark side, monochrome monitors revisited, and all of the other bad things you find in other applications that do it this way. If you read the forums of applications that do it this way (i.e., a black and white UI), you will find a myriad of complaints about this being a retro UI and how it should evolve into a more modern colorful (used sparringly, of course) UI.
