Win8Metro TestBed is RAD

I just tried Win8 Metro TestBed on my iPad and it was pretty amazing.  It works prefect for my case since I have Windows 8 Release Preview install on my closet server computer as yet I still would enjoy using the Windows 8 Metro environment once in a while.  This iPad App gives me a great way to do that.  At first I had a bit problem with the Photo App, but somehow the problem seemed going away.  Now I need to figure out how to make the Music App works with the songs that I added to the music library, but then that's Windows 8's problem, and not this app's problem.
