Indeed, value is in the eye of the beholder, but let me throw another log into the fire. If you plan to visit Vegas, Reno or A.C. this year, 400,000 points would yield $1,400 in gaming chips (cash).
However, earning enough points for a free 27" TV in one year is very cool.

But was the journey painful? That sounds like a lot of nights......
Congrats!
