been in HK for over 10 years now... four and a half of which have been in DB...can't say that i find DB that inconvenient... 10 minutes to sunny bay MTR station by bus... that takes you to kowloon etc....25 minutes to central by ferry...on the ferry you are guaranteed a seat(not so on the MTR)...
all in all, i'd much rather live in DB than Tung Chung...
that said, we are considering moving next year to either south lantau or back to sai kung...
