Just bought a Q10 off EBay. This will be my third time doing this. I sold the first two and stuck with my Z10, which I love and had zero problems.
I just miss the PKB and love the form factor of the 9900 and Q10. I will keep my Z10 for those days that I want to switch devices. I am nervous about the double typing issue too but purchased the extra warranty.
Crossing fingers.
Loving my Zed 10!!
