Everything is a tradeoff. You can make it lighter, which will give extended range given the same power source in windless conditions but at the expense of being blown around if it is windy. But if there is wind, it would drain the battery faster than it would with something with more mass since it has to fight the wind more to stay stationary/on course. You can make it foldable, but at the expense of a less rugged design with more moving parts which increases the risk of damage in the same crash scenario, or even unfolding/folding and putting wear and tear on the joints, as something more solid and durable.
The karma won't face the issues of multiple device support that 3dr did with android (and its various flavors/hardware/implementations) and ios. Supporting a single device, which is obviously android inside, will be a lot cheaper and allow faster development. Kudos there.
Lot's of different variables affect these things. There is no swiss army knife of drones yet and probably won't be for at least 5 years with the current rate of advancement and R&D. Everybody wants something that will do everything, carry any camera (with control), fly for 40 minutes etc. They are all specialized, even within their own niches.
