17 2009 Worldwide Handset Makers Basic, Feature Phones & Smartphones Sold Source: TomiAhonen Almanac 2010 WW Population: 6.7 B in 2008 TOTAL: 1.13 Billion Shrunk 5% from 2008

18 According to Gartner….  Feature phones and smartphones will overtake PCs as the most common devices used for Web access sometime during the next three years  50% of browsing is done on mobile devices

19 Desktop portable and watered down Netbook w/ Atom CPU Smartbook & Tablet w/ ARM CPU Expanded and more powerful Smartphone

20 Netbook vs. Smartbook/Tablets

21 WebKit: One rendering engine  GNU Lesser General Public License  Originally designed by Apple starting in 2002 and announced with the introduction of Safari at MacWorld in 2003  Further developed by individuals from Nokia, Google, Bitstream, and others  Easier development because fewer lines of code, uses less memory, and standards compliant

22 WebKit Gains Traction Outside of Apple  Web Browser for S60  Nokia, Samsung, LG, and other Symbian S60 phones  Google’s Chrome browser  Palm’s WebOS browser for the Pre  Android mobile phones  RIM’s BlackBerry – acquires Torch Mobile (8/09) to redo the BlackBerry browser using WebKit

23 SmartPhones not using WebKit WebKit: 5 of the 6 big Smartphone platforms –Apple, Android, Nokia, Palm, RIM Who isn’t using WebKit? –Microsoft, which accounts for 6% of the smartphones shipped in 2009

24 Mobile Browsers  Apple’s Safari  strong reviews  lacks Flash support but Apple may be looking to HTML 5  Google’s Android browser  does a nice job  could try Dolphin

25 Mobile Browsers  BlackBerry’s browser  characterized as slow and unappealing  could try Opera Mini or BOLT for speed Image source: Appboy blogAppboy blog

26 Mobile Browsers  Window’s Internet Explorer and Symbian’s S60 browser – considered clunky  could try Opera Mobile  could try Opera Mini or Skyfire Dominates the alternative browser space Presto engine located on the server Phones have less of a CPU burden Great for feature phones

27 Why this matters  Modern websites do more than display HTML pages with images and hyperlinks  More and more important transactions happen in the browser
