They're using C71+ with different WiFi module - i hope that it's better, not worse As for build quality - thanks a lot for detailed info. Just keep in mind, that C71 (and C71+) is generic name for tablet with similar hardware, yet manufactured by countless factories in China. build quality (and "peripherals" like screen, case, etc) vary *a lot* between factories. I'm not trying to defend Vivaldi here - I have no idea how their's build quality is looking. I can just hope, that they've chosen better one. /Estel
