Heya...I am in HK, a recently relocated NYCer with many decades of travel to HK.
Don't hold your breath for eink ebook readers in HK. The selection is pitiful from all I have [not] seen here.
With the exception of Chinese branded Hanvon devices [and a single white Kindle sighting], I have seen no ebook readers anywhere in HK. Not in any of the major electronics shops [Fortress, Broadway], nor even in the tech paradise centers in Wanchai or Sham Sui Po. Sony readers are nowhere to be found even in the largest authorized Sony dealers/retailers I have visited.
Reason: I am told most people who read in HK simply use their iPhones/iPads/Galaxy Tabs/whatever to read instead.
This dearth of eink ebook devices is exactly why I purchased a Kindle3 Wifi from Amazon in the States and had my family bring it over to HK last week.
Tablets? Hell yes, more than you can imagine. Cell phones, smartphones...absolutely. E-ink readers from multiple manufacturers? Nope.
sorry, but hopes this helps to shape your expectations a bit...
