True! I love my K3, especially in the lighted cover. It looks and feels solid and classy. But with carpel tunnel syndrome it is way to uncomfortable to hold for very long. Even balancing the K3 in lighted cover on my midsection while reclining a bit is still pretty tiring as my wrist will begin to feel discomfort and my hand will go to sleep. Unfortunately the K3 and K4 are way too thin for me to comfortably hold without putting them in covers. BTW, I still have this issue with the K4, but it is substantially easier on my hand and wrist.
