First, its excellent with only text, which is what I use 90% of the time.
Its only frustrating in two ways: 1) when I want to view the real article, and it constantly refreshes the page, making it unreadable, or 2) if the real article includes a video, it either starts over if you switch to landscape, or quits entirely.
So, 90% great.
