Forget about apps on the Kindle and focus on content
Amazon's ideas for this application platform include travel books, cookbooks, and word games and puzzles. I would rather see Amazon focus on opening up the Kindle to standard formats (EPUB and Adobe Digital Editions) like the rest of the ebook reader world so you can load up local library content or ebooks purchased through various other outlets. One reason I love my nook is that it has support for multiple content sources, most of who send me discount coupon codes every couple of weeks so that I rarely pay full price for a book. I believe content is king in the ebook world and not applications, web browsing, RSS, and all these other services that are much better supported on a notebook or smartphone.
