After Apple’s latest iOS 4.2 update, the iPad has a lot of new features, not the least of which is Apple’s reasonable take on multitasking, Folders and a unified email inbox — all of which are features iPhone 4 owners have been enjoying for months now. Also awesome is AirPlay, which lets you stream music and video to an Apple TV; and AirPrint, which lets you wirelessly print without worrying about printer installation and drivers — although it must be noted that only a handful of HP printers support AirPrint right this minute, so the feature isn’t particularly ready for widespread action just yet.
