I liked it. I know this episode has had a polarizing reaction, as some people were angry at what they perceived as gimmick-y and full of product placement. But actually, I thought this was very clever, funny, and oddly insightful about the way technology works in our world today. Let's look at the plot.
Claire is in the airport, waiting to board a plane back home after a business trip. The whole episode is just Claire's laptop screen, as she Facetimes and chats with her family members, looks things up on the internet, manages her to-do list, etc.
Apparently, Claire and Haley got into some stupid fight, and Claire is worried when Haley won't answer any of her messages. Claire has to deal with Phil, who won't stop playing video games, Alex, who just wants her mother to read her college essay, Luke, who gets a Mohawk at Jay and Gloria's house without asking, Cam, who keeps asking for special popcorn from Chicago, and Mitchell, whose birthday she almost forgot. Throughout all of this chaos, she can't find Haley.
Claire uses a fake Facebook profile to check Haley's page and sees that Haley "got married." She also tracks Haley's cell phone and discovers that she's in Vegas! The whole family freaks out, thinking that Haley has gotten married. To whom? Andy! Apparently they were together last anybody heard from Haley. Then, a package comes in the mail for Haley - it's a book on pregnancy! Oh no!
