Usability 
The official mobile site of the 2010 Winter Olympics has ticket information, live results, medals, schedules, athlete bios, teams, news and photos. The news section uses a feed from the AFP news agency. The feed items are nicely formatted for mobile and are full items not excerpts. The sheer quantity of news in amazing and a bit overwhelming. The games haven't even started yet and the site already has 65 pages containing over 900 articles in its news section! Unfortunately there is no way to search the news. At 80 KB this this another smartphone optimized site.
Vancouver2010 also offers a free iPhone app featuring a location-aware spectator guide, maps to all the venues and real time results.
