Mobile Handset OSes

Originally developed for the iPhone, it has since been extended to support other Apple devices such as the iPod touch, iPad and Apple TV.
Apple's App Store contains more than 300,000 iOS applications
iOS 4.3 was released to the public on March 9, 2011, 2 days before the iPad 2. In addition to earlier features, the public release of iOS 4.3 includes many new features such as a Nitro JavaScript engine in Safari, making Safari run up to twice as fast.
iOS 5.0 and its features were announced on June 6 at the WWDC 2011 keynote address. The expected release date is believed to be sometime in the third quarter of 2011. iOS 5 will introduce the iCloud service and the Notification Center, as well as improvements to native apps such as Camera. The operating system also features new applications, such as the "Reminders" app and " NewsStand ", an application resembling Folders and iBooks.
iOS IOS

Fastest growing mobile OS
Over 300,000 Android activations a day
Android overtook iOS as the dominant OS in US during 2H 2010
First phone launched HTC G1 in 2008
Currently an OS of choice for Motorola, HTC, Samsung, Sony Ericsson, among others
Software updates every few months
3.2 Honeycomb released at July 15 2011, is "an incremental release that adds several new capabilities for users and developers". Highlights include optimization for a broader range of screen sizes; new "zoom-to-fill" screen compatibility mode; capability to load media files directly from the SD card; and an extended screen support API, providing developers with more precise control over the UI. [62]
Future releases Ice Cream Sandwich is said to be a combination of Gingerbread and Honeycomb into a "cohesive whole". [51] In September 2011, Eric Schmidt stated that Ice Cream Sandwich " is being released in October/November. " [63]
Android OS ANDROID

Native vs Web Apps

“ Native” Apps:
Written in a programming language for a targeted operating system
Apple iOS Devices: iOS SDK, using Objective-C
Android Devices: Android SDK, using Java
Have access to all features of the hardware
Camera, GPS, Accelerometer, Microphone, etc.
Are distributed via the respective app “marketplace”
iTunes App Store, Android Marketplace
iOS apps are subjected to rigorous testing/acceptance process; Android apps are submitted to the Marketplace with little oversight
Development fees:
Apple: SDK is free (registration required), $99 to submit apps to App Store
Android: SDK is free, $25 to submit apps to Android Marketplace
Native vs Web Apps

“ Web” Apps:
Web-based applications written with traditional web programming languages
HTML/CSS, Javascript, PHP/.NET/JSP
Have limited access to device hardware (depends on platform)
Can be used cross-platform (some restrictions apply)
Most are intended to be used when the device is online; some have capabilities for offline use
Most platforms have some semblance of a “web app store,” but the stores and their contents vary widely
No centralized marketplace for all platforms
Native vs Web Apps

$$$ (or the potential for $$$)
iOS App Store provides a “filter” for apps, so users have at least one means of gauging their worth
All app marketplaces provide ratings, comments, rankings
Interacting with the hardware provides significant app potential
Users have been “trained” to search the markets first
Native Apps: Why so Popular? NATIVE

Can produce vivid, dynamic websites with high levels of interaction
Can integrate web services (no need for local data sources)
HTML5 affords video, audio input
CSS3 includes animation, some 3D rendering
No need for Flash (!!!!!!)
Browser support varies widely
Most data-driven features require the app to be used “online”
Web Apps: Html 5 + CSS3 + Javascript DEVELOPMENT

Eclipse IDE for Android

Xcode interface

Shift to Tablets

iOS and Android
Are biggest players
Other Tablets
still a possibility
Tablet Market Share by Manufacturer

Tablet Market Share by OS Note: QNX = Blackberry

Re-use of code across platforms from mobile
Different form factor size an issue
1GHz dual-core Apple A5 custom-designed,
high-performance, low-power
system-on-a-chip
2 cameras
9.7-inch (diagonal) LED-backlit glossy widescreen Multi-Touch display with IPS technology
Three-axis gyro
Accelerometer
Ambient light sensor
iPad

10.1-inch capacitive screen
a 5MP HD camcorder
1 Ghz dual core Tegra 2
Barometer, accelerometer, gyroscope
Motorola Xoom (Android 2 nd Gen. Example)

Blackberry?

Started out as contender,
HP suprisingly killed it when
sales were less than expected.
Available for $99 for a limited time.
Wi-Fi 16GB
9.7-inch diagonal LED
webOS
1.5Ghz processor
HP Touchpad?

Windows Tablet Interfaces….
Still a possibility – remember the Symbian OS?
Was first to market, in early 2000s

“ Apparently Apple has agreed to a price three to four times higher than normal in exchange for reserving a large portion of the highest quality screens the manufacturer.”
Apple’s Lead in the Tablet Market Apple’s network of retail stores , with knowledgeable employees and the periodic hysteria-inducing product, you can interact with the iPad inside the friendly confines of an Apple Store cannot be matched by competitors at the Staples, Walmarts and Best Buys of the world. • Apple has put together a decent moat on pricing , so much so that Asus declared no intention of jumping into the tablet market. • Also, integration of software. The presence of dozens of killer apps, downloadable immediately – or in many cases, already in the possession of the owners of iPhone or Touch devices

Still can use Eclipse and Xcode (or Visual Studio for Windows)
However, 7 or 10 inch form factor? Still debatable
Applications for data entry (POS, Medical)
Next gaming platform?
Replacement for netbooks/laptops?
Developing for Tablet

Mobile apps/platforms are still changing, even as they mature
Tablets are still in a state of flux
Possible code-reuse, however form factors aren’t the same
Shift from laptops to tablets?
In conclusion
