Data Courses on Coursera

The desire to gain expertise in big data doesn't show any signs of going away, nor is there any slow in the flow of training on the topic: there's three courses on Coursera all starting at about the same time:

• Computing for Data Analysis (Roger Peng, JHU)
• Computational Methods for Data Analysis (Nathan Kutz, U of Washington)
• Data Analysis (Jeff Leek, JHU)

They all start next month, January 2nd, 7th, and 22nd respectively. The first looks like an intro course covering basic R programming and analysis basics, and lasts 4 weeks. The other two look like more in-depth analysis training and last 10 and 8 weeks.

Is anyone planning to take any of these courses? Which one?
