Conclusion
HTML5 a Solution to Homogenize Mobile Space?
Users mostly still decide Pro App
Added Interactivity
Faster Start-Up
More Network Independent
Mobile: HTML5 or App?
Interation Intense
Data Intense
HTML5 or Plug-In based RIA?
Today, Browsers should not require a Plug-In to play Multimedia Content.
Today, Line-of-Business Applications with lots of Logic are very hard to write in JavaScript.
