They are not trying to get noticed by MS (in hopes of a career)! They are trying to make new trends in UI design! Microsoft is just copying Mac UI slowly and gradually! I have seen many Windows UI elements have a resemblance with Dribbble designers' designs!!! Maybe the UI designers are copying Microsoft or vice versa!
IMO Microsoft Windows is the rule of 50-50! 50% rubbish and 50% perfect! The big problem is users are wasting their time to make the 50% of rubbish things better (by patching dll, tweaking registry keys and ...). It takes more than one or two years to get used to it, and then Microsoft releases a new version of Windows! And everything starts again!
