Looks like a Metro only app right? No 32 bit app? 

+1 for drawboard PDF. It is a modern/metro app but works well. But I quite like the metro interface (I was a windows 8 fan, so some may question my judgment).

I downloaded it and I must admit, I quite like it, and the price is hard to beat. 

I liked PDFAnnotator

For my part it's because I bought PDF Annotator years ago and like it so I've never felt the need to upgrade to a "modern" app.
