The display is really great and in the settings you can switch off the automatic brightness adjustment, power saving mode from 30% and the fast disable the display. Thus, it illuminates me easily, for example for 30 minutes with the same brightness.
When I clicked on updates the first time I was surprised to find the same 3 System updates were installed. Very good! That all went very quickly and without any problems.
The pre-installed apps are limited and can also be easily uninstall.
The CPU is quite fast, if not exactly an update running in the background, I did not notice any lag or even surfing with pre-installed Chrome browser is very fluid.
With the expansion memory (64 GB has been around for 40) one is priced at half of an iPad Mini with 64GB memory. Thus, this device is a real bargain with a top hardware equipment! I can only recommend buying.
