"These are a few of my favorite things" #4 - Apple's iMessage app

This is an odd one to have on the list since I don't text very much and because I just upgraded to Mountain Lion a couple of months ago, but this is one of my new favorites. I love how when someone with an iPhone/iPad sends me a message, it pops up on my computer as well (and that I can send "text messages" to iPhones/iPads from my computer). More than half of the people I'd want to text with are on Apple mobile devices, so this is really convenient as a way for me to avoid texting from my phone!
