One of the little-mentioned features in Apple’s new iOS 5 is the addition of Reader in Mobile Safari. Reader, which was introduced in desktop Safari last year, allows a user to click a button in the browser address bar to render a webpage in a user-friendly, text-only format.
Reader instantly turns mobile webpages that may be poorly designed or have small fonts into elegant and highly readable pages. All ads, photos, and graphics are stripped from the page. Reader also merges articles that may be spread across several pages on a mobile website into a single scrollable page. And as with all things Mac, the handling of typography is excellent.
Reader is based on technology licensed from Readability, which also created a bookmarklet version for desktop web browsers and is embedded in the Amazon Kindle and popular iPad applications like Flipboard and Reeder.
Below is an article from the Chicago Tribune using the normal Mobile Safari display and Reader. I know which one I’d rather read.
