We've had one for a month. It's for business so we got the 385 model. Still breezes through anything, supports 4 off 4k monitors and runs cool and quiet. Plus we saved a lot of money. Added another m.2 ssd, and some external connectivity. Very impressed.
I was waiting for AMD to release the 9000G to build a PC to replace a decade old A8-7600 build. In the end we got fed up and ordered the Z2 Mini G1a. Reports suggest the 9000G isn't that great.
