Hi everybody,

I am seeking out a suggestion for a PDF annotation application for Windows 8 Metro UI from the Windows Store. I tried to buy Drawboard PDF from the store when it was on sale, but the checkout system wouldn't work for me. Because of that I am conscientiously objecting to buying things from the store for a while. What is the second best app for PDF annotation? Or, more specifically, what is the best free app?

Mainly, I just need to do highlighting, bookmarking and possibly adding some small notes.

I have the full version of Adobe Acrobat on the desktop, but I am looking for something simpler and lighter for the Metro interface.

Any suggestions are appreciated.
