If you’re anything like me, you use the Messages app in OS X Mountain Lion to keep chatting with those iMessage-happy iOS users in your group of friends when you’re at your computer. Nothing’s more annoying than having to pick up my iPhone while I’m on my Mac, just to text someone back.
With the OS X Messages app, I can just chat with them as if they were on any other instant message client, using the full keyboard on my app instead of the tiny one on my iPhone. Sometimes, though, friends might send along a web link. When I don’t want to have to click through to see it in Safari or Chrome, I preview it right in Messages..
