Usability 
Prestigious international affairs and business news weekly The Economist, has quietly dropped the pay wall on their mobile edition. The mobile site which used to cost $7.95 a month is now completely free.
The Economist Mobile includes a selection of articles from the paper's main on-line site and the print edition. There are typically around 50 articles on the mobile site divided into News, Politics, Leaders, Business, Science and Technology and Business Travel sections. Most articles include single mobile sized image.
The site's design and layout is generally pretty effective in phone browsers. Page size is under 20 KB and scrolling is minimized by the hierarchical menu structure and giving each article its own page.
