Thanks. I even saw a program on TV that compared the best places to shop (electronics included) in the world and Hong Kong was up there along with Singapore and London. I think it was the Travel Channel or something like that.
I guess I was right when I went there last April and found everything to be quite more than the US.
Regarding the phones, getting an unlocked GSM without service in the US is a pain, so it might be easier to get it there even if it costs a bit more.
In any case, I think the only good deals I might find there will be some "authentic" $10.00 Rolex watches...
