It's estimated that as many as a quarter of the gifts exchanged this Christmas had to do with technology. But many people don't have any idea how to install a GPS, set up a computer or start downloading music onto an iPod.

Those were some of the most popular gifts this year, and fortunately most electronics stores have experts on hand to help customers through it.

David McPhearson and the rest of the Geek Squad at Best Buy helped post-Christmas customers on Wednesday with a lot of iPods and a lot of computers.

One of the most thankful customers was Faye Latta.

"David was our guy that guided us and identified the virus and is fixing it. I'm so happy," said Latta.

McPhearson said the job was busy but rewarding.

"That's the best thing because you were the person who could fix something that was wrong that day," said McPhearson.

Another Geek Squad agent, Trey Godfrey, said he has been going house to house responding to Christmas emergencies.

"A lot of people are getting MP3 players, portable DVD players and things that attach to your computer this year, and we can help you set it up and train you how to use it," said Godfrey.

He explained that he enjoys sorting through the confusion that most people would consider a headache.

"It's nice to be able to help people embrace technology as the geeks have, and it's fun to see the smiles when they know it works," said Godfrey.

Bringing your computer in to Geek Squad for a simple diagnostic check could be free, but for a house call customers are looking at a minimum of $89 and up to several hundred dollars, said Geek Squad agents.
