Seriously, the K2 and DX share many features -- and can use the same accessories - like the charging cable. And have similar menus of features.
The K1 is perfectly functional - but if I was Amazon - what is my motivation to continue developing/updating its firmware, supplying replacements for damaged units, etc. And if I am a developer, what is my motivation to continue making accessories or software apps to enhance its use? If this is a major monetary purchase for you, for the long run, the K2 is probably the better choice.
