noun: The elated feeling-one part refreshed, one part hip, and the rest Narcissistic-one receives upon downloading the newest (oh, wait...not anymore) version of Apple's operating system (for any device); the iHigh is directly followed by the iFail, or the inevitable realization of utter impotency in the face of Apple's conspiracy-not to mention a dangerously successful business model-to constantly outsmart its consumers, who nonetheless impulsively continue to purchase Apple products.
Man, when the App Store popped up with the iOS6 update that included Siri for the iPod touch, I got such an iHigh; then I realized that iFail...my iPod Touch 4th Gen. doesn't have the necessary hardware for Siri!
