The site's Q&A section reveals a few bits on what we can and cannot expect from the browser. First, the good. The browser supports full stylus-based controls, for scrolling and jumping between pages, and even for inputting characters through direct handwriting or via a software keyboard. The browser keeps track of previously entered phrases so you won't have to enter them again.
Now for the bad. The browser won't be capable of displaying Flash and PDF, nor will it support video and sound. While you can save bookmarks to your favorite pages, you cannot save images or other elements of pages.
