Why did Huawei, a maker of Android devices hand out iPads to attendees, and not provide a proper Wi-Fi connection?
I'll tell you why. Because like every Chinese company I've ever dealt with they have no f*#%ing clue what they're doing.
The only way Apple (and others) get quality from their Chinese manufacturers is by constantly looking over their shoulders making sure they provide what they're contracted to.
Go to China, have a good look around the plush head offices of some of these big companies. The toilets overflow, the roof leaks, and the carpet doesn't fit properly.
China does cheap really well, but it's completely half-arsed.
