I second it.
I did my share of shopping around in both US and HK.
The prices of electronics are definitely lower in US especially in Calfornia and New York City than in US, with a few exceptions e.g. cell phones especially triband GSM phones. In US, we seldom buy our own phones because of the package deals provided by the vendors. But, in HK, you can get a brand new Nokia 3100 for less than $50 USD. I just got one from People with a $200 HKD rebate.
I bought a brand new 21" TV from Fortress a few weeks ago for $890 HKD, but I can get it for less than $100 USD from a lot of stores in Northern California with more features and better video/audio quality. The people in Fortress kept telling me that the $890 HKD TV was made in Turkey and they seldom carry any electronics made in China. I still don't know why. Man, in US most of the electronics from PCs to consumer electronics as well as small household appliances are from China directly or indirectly. Believe me, I just don't trust those so-called Made in Japan models anymore. I don't think they are really made in Japan afterall.
