I started a product newsletter and I need to know if it sucks or not

This weekend I created a newsletter.
http://lessonsinproduct.com/

It's about how products go from being “that new technology” to the thing they are today.

I take 1 product (either physical, digital - it can be anything) and write about:

• Why I love it
• How it started
• Lessons it can teach us

I've written 2 so far:

1. Slot Machine
2. Jeans

–––

What do people think?

Honest feedback appreciated.

Thanks in advance
