I recently attempted to use the Nook Touch web browser for a project and found that it was way too slow and hopelessly broken (no support for onmouseup/onmousedown, no support for touch events, etc.).
To avoid these sorts of problems with my next hardware purchase, I wrote up a trivial test page that tests the core HTML/JavaScript functionality that I need for this project.
Could somebody with a Kobo Touch please go to the following web page, follow the instructions, and post back your results? Thanks.
