My turn
I wanted a K-01 because
1. It allows me to use my cool pancake lenses with it. Yummy!
2. The on board flash seems to be sitting a lot taller than my K-7 and K-x's. So I am hoping that using the on-board flash with my DA14 will not cause a dark spot in the photo (sometimes using DA14 in a lowly lit environment need a bit of fill flash).
3. It uses the same battery as my K-7 which I have a couple of. Save some cash here.
4. It has that cool sensor from K-5 and is lightyears from my humble K-7
5. Styling wise, it is unique and small. I like this in a camera. Beauty is in the eyes of the beholder.
6. street shooting - I am guessing this will be less obtrusive? people seem less noticed by a camera using live view.
7. Video mode - I never thought i would say this (because i never really use the video modes on my K-7 and K-x that much) but the full HD capability on the K-01 interest me alot. I think i will shoot more video from now.
8. full liveview mode allows me more accurate focusing (I hope so) because there is less back/front focusing problems with lenses.
