Unfortunately I am :-) Thank you for the reply. Actually you should not fear rational people: if your content is good enough they will upgrade!

If there any upgrade pathes between the plans? Let say that I buy the starter plan, like the content and want to buy the plan with the videos. Should I pay the full price?

I have only read the first two chapters (setup and Javascript an overview).

The content do not look bad (but I have not read node.js specific parts yet so I can't really tell). The bad part is that it would need some serious proof-reading... Some sentences are missing words or are hardly understandable and there are some mistakes in the code.

Minus the fact that there are some DRM in the Kindle books which is rather anoying.

PDF is an open standard, the Kindle format is not.

Sure, you have other options to read Kindle books without a Kindle device:

* On the web or on your iPhone/iPad https://read.amazon.com/

* On Android: https://play.google.com/store/apps/details?id=com.amazon.kin...

I would say Tripadvisor. Check the culture paragraph here http://highscalability.com/blog/2011/6/27/tripadvisor-archit...
