In March 2011, Apple finally announced support for full 720p or 1080i HD video output for the iPhone 4, iPod Touch 4G, and iPad 2. However, you need Apple's $39 Digital AV Adapter to send that HD video and audio to a TV or monitor, whereas many Android-powered smartphones offer a built-in Micro-HDMI port that only requires an inexpensive $5 cable to run video to your TV.
Now that Apple's added AirPlay mirroring as part of iOS 5, if you have an Apple TV, you can stream video wirelessly to your TV via Apple TV (what's on your iPad 2 or iPhone 4S' screen is mirrored on the TV). That's nice, but it's worth mentioning that the Apple TV is a $99 accessory.
