Thanks to Steven Troughton-Smith for testing this and the photos.
First, the NookColor as it was never meant to be — with full Android access:
And one ginormous photo:
As for using it, he reports: It takes about 1.5 seconds to render the page, it’s readable without pinch-zoom (and pinch zoom is not remembered page to page, and it takes about five seconds to re-render in pinch zoom). The PDF is treated as a set of images without the ability to select, copy, or highlight text.
It’s interesting that per-page render time is faster than the iPad. On the other hand, the iPad keeps three pages fully-rendered at one time — maybe that accounts for the seemingly longer per-page render time?
