Just over 30 years ago I bought a Pentax Auto 110 for backpacking. I was hard on that camera, but it survived a number of years as my photography interest grew. I went on to own an ME Super, a couple of MX cameras, and my prized LX. These were every bit as sturdy (and more!) as the tiny Auto 110 sibling they replaced.
I lost my photo gear to a house fire many years ago, and let my photography interest wane. When it was finally revived, I kept an open mind about all brands and borrowed and rented several cameras. In the long run I ended back at Pentax with the K-x due to the cost to IQ ratio. Still have it, but it's been mainly replaced by a K20D. Having spent so much time with the MX and LX, it's just a joy to have so many dedicated controls in a modern camera body. To date I have yet to try any other dslr - of any brand - that is as "transparent" in use for my style of shooting.
Though I have to give the K-5 a try; that one might change my mind
