Thanks for that.

Unfortunately, all of the Sound & Vision outlets at HKIA were out of stock of the device this evening and don't know when they'll get more in. "Maybe next month", they say.

Surprisingly, there were two other people in the shop at the same time as me trying to buy the Pokefi, so it clearly is very much in demand.

I'll try again next time I pass through HK, or will see if it becomes available on a CX flight.
