Thanks for your feedback. We'll be doing some research on improving text legibility, especially on the 7" screen. If any of you want to chime on the elements of the display that you're finding challenging to see, that would help us evaluate where we need to look.
As for the brightness thing - we intentionally don't boot at full brightness to preserve night vision settings that may be explicitly set. We'll be looking into possibly changing the software to have a minimum brightness setting on boot that's brighter than the dimmest setting (which isn't very visible in any daytime light, admittedly, but is great for night, and better than most other competitive units). Additionally, if you use the AUTO setting, the light sensor will adjust the display for the ambient light setting. And, if you don't like the levels for different ambient light states, that curve is user-adjustable under LOCAL SCREEN SETUP > BRIGHTNESS SETUP.
