So the Kindle is popular these days, what with the larger size coming, and the iPhone app. We've tested it out and used it (not as cool as the Kindle screen, but decent enough for passing an hour or less somewhere - don't try it for long reading), and it works pretty well... except the book browsing/buying function. That sucked.
Before this latest update on Amazon's part, you were actually directed to Amazon.com in your Mobile Safari... and it was the full version of the site, where you would browse through books on your iPhone screen in a nice layout absolutely lame design.
