In 2003/04 I spent a year in the United States, working as a User Interface Designer for Siemens Medical. To document my stay I bought the smallest camera I could find. (Yes, this was before phones had cameras or were smart). I picked the Pentax Optio S4i.
The S4i was my first real camera.
It fits in the palm of my hand and I always carried it with me. It had glorious FOUR megapixels and it was shiny and perfect – but only until the S5i came out. The S5i had even FIVE megapixels and it allowed me to customize two buttons (instead of one). This was just too good. I bought the S5i and took some good pictures with her over the years.
Actually, I took my best picture with it.
