Personally, I think this is a great deal. People need to realize what you're paying for: An official, optimized Chromebook virtually eliminates all computer headaches. I know that most people I know would love one and will be happy to pay the small price for:
A computer that gets faster with time, not slower.
No additional software to purchase!
Absolutely no anti-virus needed.
Getting directly on the internet.
Extremely secure experience (Verified Boot)
The setup takes minutes, not hours.
I think all of that makes it very worth it.
