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)
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?

Apples Lead in the Tablet Market Apples 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 arent the same Shift from laptops to tablets? In conclusion
