I've just bought a K-S2 as my first DSLR. My last camera was a Super-A, so I do mourn a little bit the switch from a metal-body camera to the plastic lumps that are the entry-level DSLRs today. The camera body does feel robust, is nicely compact and fits my hand well. The folding kit lens does not have quite the same robust feel, and is a bit of a faff to get out and put away. When locked out it is solid, but doesn't quite have the "hand presence" of a chunky zoom. I'm also finding the zoom ring to be a bit narrow, although that might just be a case of practising enough for my fingers to go to the right place. On the other hand, it is small and portable, and when you're out on the hill all day and have a lot to carry in your rucksack for the family, small and portable is a distinct advantage. As is weather-resistance

My first camera was a Rollei 35 with a lens that collapsed back into the body, which also felt wobbly and delicate when not locked out. Never got damaged though, and we went to a fair few wild places together.
Video I'm not worried about, but if I was I think I would have gone for something else.
And I do love the way Pentax are trying to alleiviate the "black plastic lump" thing with their colours.
