Does it receive regular monthly security updates or the device is left unpatched and thus vulnerable for the whole lifespan like many other Android devices ? It is more like a cheap toy rather than serious tool.
It's a shame a big company like Lenovo was not able to secure Atom X7 chips, which would've made a noticeable improvement in the user experience. The shame is they probably chose the cheaper inferior part to pad their margins.
It's also ironic that this device caters to graphic designers, yet "the screen may have too high color deviations for professional use."
