To add just one thing to this (which covers most bases I think), it really depends who you're pairing with. I've had really great times with a buddy at work, paired up, complementing eachother's skillsets, getting things done, and having a great day at work. And I've worked with far less agreeable personalities who're always right about everything, in your face, and just plain not enjoyable to be around for any extended period of time. That's probably the biggest takeaway from pair programming for me. With someone good? Have a wonderful time accomplishing a lot. With someone bad? Have a stressful time... maybe accomplish something.
