Great product experience wins

I often like to remind myself the importance of product experience. For me, one
great example recently is Kindle Word-Wise. Word-Wise is essentially showing a
short 4-6 words vocabulary definition above a word for difficult words. The
definition is based on context and very concise. This is extremely helpful for a
non-native speaker like myself who wants to get a better hold of what author
is saying.

I used to pirate books from the internet and send them to Kindle. It was cheap
and essentially the same as buying an original book. However, after Word-Wise,
it completely changed my behavior: I started buying original books and would
spend on average $100 per month on books (5 books per month, $20 on
average per book).

I am guessing that underlying this feature is technology like LLM, which
identifies definitions based on context and gives a very concise version of that
definition. This way of leveraging technology into a product delivers beautiful user
experience and is economically viable.

This taught me that improvement on end-to-end product experience makes a
HUGE difference on customers.
