Information regarding potential future products is intended to outline our general product

Performance is based on measurements and projections using standard IBM benchmarks
in a controlled environment. The actual throughput or performance that any user will
experience will vary depending upon many factors, including considerations such as the
amount of multiprogramming in the user’s job stream, the I/O configuration, the storage
configuration, and the workload processed. Therefore, no assurance can be given that an
individual user will achieve results similar to those stated here.

Platform Philosophies
Raising Developers
Android iOS

12
  iOS = developers fall into the pit of success
  Android = developers are free to succeed or fail
  WebOS ~ failed because it was a copy of iOS, but much weaker
  WP7 ~ watched WebOS and made strict rules, but differentiated

13
  Button hit areas for iOS buttons as in this this case “New Tweet” are larger than the button.
This makes it more difficult to have buttons under that button as the Android version does.

14
  Standard button style for iOS generally involves rounded corners while Android and
Windows phone feature square corners. See Facebook for iOS vs Facebook for Android.

Human Interface Guides
Android iOS
WP7

16
Human Interface Guides
  Android
– HIG 2008
– HIG 2011
  iOS
– HIG Evolution 2008-Present
  WP7
– HIG 2011

17
Screen Dimension & Density Differences
  Android
– 16 Potential Screen Dimension/
Density Combinations
– 4px Exceptions
  iOS
– 2 Potential Screen Dimension/Density
Combinations
  WP7
– Strict (watched Android challenges)
  No Reflow on Mobile

18
To Skeuomorph or Not
  iOS = Skeuomorphism
– Stylize everything
– Lots of depth
– More touchable
– Literal UI texture
  Android/WP7 = Simple/Flat
– ‘No Chrome just Content’
– Less clutter
– Flat
– Huge differentiator

19
The Back Button and Other Differences
  iOS = No Back Button
  Android = Back Button
  Device Shake (not in Android)
  Swipe in table view (not in Android)
  Long Press on list view (not in iOS)
  Touch & hold editable text (Popup
menu with copy past options in
Android, display magnified view for
cursor positioning in iOS)
  Scrolling scrollable area beyond limits
(Borders highlight in Android, Bounce
effect in iOS)
