At 5K, the price is right (my in-person master's was 22K, although my employers covered most of it) but be aware it's not the missing piece to catapult you into superstar developer earning 170K/year. Honestly I think your time is better spent working on real projects. In my CS master's program I met many students with no real-world experience. One was a paralegal before school, and after he graduated he became...a pa…
There's really not much off that to be had -- one introductory theory + algorithms course, one course on algorithms and complexity for parallel and distributed programs, and after that just a few domain-specific things -- image processing and machine-learning algorithms.
I thought the program was worthwhile because it was cheap and flexible. I could watch lectures on the train on my commute. Quality is mixed, though, and other degrees or (as you say) real-world experience could prove more valuable, depending on their own quality -- I wouldn't assume that any programming experience is better than this program.
