FWIW, I've purchased several Dell desktops and notebooks, and found that their typical delivery time is less than half that which they quote. I am presently typing this from my Dell Inspiron in Bangkok, which has traveled around the world (or the equivalent) about 20 times with only a few cosmetic blemishes and minor housing cracks to show for all the wear and tear.

As far as Hong Kong electronics go, be careful. There are some legitimate outlets and bargains, but it takes work, research and experience to find them. For example, I decided to get a Nokia 8890 phone last year. I went back and forth between a dozen shops until I was able to find one with all authentic accessories (e.g. batteries, cases, headphones) that was not grey-market. And even at that, I had to bargain hard, and make them go into the back room to bring out the real accessories they removed from the box.

The warranty problem in Hong Kong is a real one. There is a lot of grey market stuff floating around, especially in the TST district. For example, at least 3 out of 4 Rolex dealers have no problem making up a Rolex to the customer's specs: case, dial, band. All authentic parts. Except the watch is produced by an unauthorized dealer and will not be covered by a Rolex warranty or be serviced by Rolex authorized service centers, despite whatever paperwork and assurances are provided by the shopkeeper. Caveat emptor.
