iPad users can now run their favorite apps and switch between them instantly. Users can organize their apps with drag-and-drop using Folders, and Mail now features a Unified Inbox, fast inbox switching and a threaded message view.

Game Center allows iPad, iPhone and iPod touch users to challenge and play friends or be matched automatically with new opponents, showcase their scores and achievements, and discover new games their friends are playing.

AirPlay is a new feature for streaming music, video and photos wirelessly from iPad, iPhone and iPod touch to Apple TV, transforming Apple TV into a great accessory for iPad, iPhone and iPod touch. iOS users also will be able to use AirPort Express and AirPlay to stream wirelessly to any stereo or powered speakers, or directly to AirPlay-enabled speakers coming to market in the months ahead.

AirPrint is a next-generation Wi-Fi print architecture designed to simplify printing by eliminating printer drivers. A selection of AirPrint enabled printers including the HP Photosmart, HP LaserJet Pro and HP Officejet will be the first to support printing direct from iOS devices. iPad, iPhone and iPod touch users can tap to print their documents or photos wirelessly to any printer that supports AirPrint.

The Find My iPhone (or iPad or iPod touch) feature is now free to use without a MobileMe subscription and helps you locate your missing device. The Find My iPhone app is a free download on the App Store and lets users easily locate a missing device on a map and have it display a message or play a sound. Users can even remotely lock or wipe data from a lost device to protect privacy.

Other new features that iOS 4.2 brings to the iPad include: the ability to rent TV episodes directly to iPad using the iTunes App with a 30 day viewing window and a 48 hour session window once playback is started; the ability to easily find and highlight specific words and phrases on web pages in Safari; enhanced enterprise support so businesses can take advantage of stronger security features, new device management capabilities and improved enterprise integration;  accessibility enhancements; and support for 25 additional languages, including Korean, Portuguese and Traditional Chinese.

You can browse the web, read and send email, enjoy and share photos, watch HD videos, listen to music, play games, read ebooks and more, using the Multi-Touch user interface. iPad weighs 1.5 pounds.
