Well the new Q1 has arrived and I have to say I am very pleased.
The unit appears to be very responsive I never owned a Q1-U 800Mhz version but did have an opportunity to play with one.
Comparing that to the Q1 Ultra Premium at least to me there appears to be a significant speed improvement I have a piece of software that does RF propagation analysis that choked on the Q1U but ran well on the Q1U Premium.
The unit is a bit heavier but still quite comfortable to hold for long periods. I like the improved keyboard while still not something I will use much at least now it is usable where it really was not before.
The battery life seems very good I used it heavily today and did not run out of battery.
If I can answer any questions for anyone let me know.
