My wish list for the KX3 would be to serve as K2 replacement, price/performance wise. While I could list some UI and under-the-hood improvements, and I agree with Tony's suggestion below, I want to make a form-factor suggestion. I'm imagining the KX3 repackaged so that it can be used alone as a

Actually the KX3 is pretty hard to improve, but the one obvious consideration is that the internal batteries should be LiPo. Another possibility would be a different way to generate the oscillator freq to ensure super-stability; even after the refrigerator procedure mine drifts -3 or -4 Hz in a
