Looks good, I really need to work on my site and I'll probably also use a simple layout. But I did notice a couple things while viewing it on my phone (samsung galaxy epic). First is that there is no space on the left border so text is right to the edge, this isn't a huge deal as the text is still readable. And second, the youtube videos overlap some of the text, this is a big deal, for me at least since I use my phone to browse the web alot.
EDIT: On my nexus 7 the videos don't overlap the text, but the text on home page is still aligned to the edge of the window.
