Gigabyte AI Top Atom - any experience positive/negative

Yeah I have upgraded my older atom, one with nov25 bios, few day ago - happy 122 gb camper now as feb26 model. I will upgrade feb26 too. Note of caution - first restart indeed takes time and minutes of black screen. but what is important - after it restarts and start working normal - second restart also doing something to bios/uefi but completely silent with blacksreen, sitting for 5 minutes seemingly dead. do not be tempted to shut it down! it will start and all will be ok. according to many reports losing patience and shutting down with power button will brick it!
