PSA from a current owner: This thing comes with preinstalled adware. The hardware is nice, the software features are generally nice. I'm happy with the purchase. HOWEVER, make sure you go to settings and force disable these two apps: tabtop picks, appservices.
Both will show you nagging notifications which ultimately force you to install some garbage apps. Literally taptop picks impersonates a "finish setting up your device" popup as you'd expect to see from google but asks you to pick some apps from a list of junk with the kicker being three of those apps are selected by default and CANNOT BE UNSELECTED. Canceling out of the setup will simply cause the same notification to appear again a couple hours later. Appservices does something similar. Neither app appears in the usual app list and must be manually searched for in the settings search in order to disable.
Pretty disappointing considering Lenovo got lit up for doing things like this on a previous android tablet and their CEO promised to "do better".
