After using a Q5 I was considering a Q10 for the slightly better specs. Then I saw one a few days ago and didn't like the screen--a very dim amoled. No comparison to the Q5's bright LCD.
Plus, the Q5 has crazy good signal strength. I have a couple other recent posts showing the Q5 and Sony Xperia Z3 side by side with the Q5 showing a 28 dBm better signal on the Q5. Huge difference!
The Q5 also has 3-6 dBm better signal than my passport.
My wife's iPhone 5 showed the same 28 dBm worse signal as the Z3 so you would notice a big difference with the Q5.
