haha, u're welcome! then i'll give u a few tips~
well, most people would come to HK to buy some light electronics, like computer components, MP3, cell phones, laptop (they say it's a bit more advance and cheaper)... dont go to those small stores, go to a shop called 'Broadway', they have many branches everywhere, like MK and CWB, with better quality and fair prices.
and for
shopping,
- if u really want to shop new/fashionable/interesting/worthwhile stuff, definetely go to MONG KOK(MK), CAUSEWAY BAY(CWB, AND TSIM SHA TSUI(TST)... just focus on these few places, u can find almost everything there... that's where we young ones hang out and people usually shop at and those place has shops EVERYWHERE, just shop as detail as u can and u'll find some gd stuff.
(just follow the crowd where people are all going up to, gd stuff are usually there, not quite in the huge stores u can see on the street)
- they have all those famous brand (like Chanel, Gucci, Prada, Burberry) in CWB, TST and Central. when u're in TST, check out the Ocean Terminal, a huge gd mall. there's a new big mall in Central called IFC, might worth a trip.
- some people would like to check out the Women Street in MK, cause it has numerous fake stuff like Gucci, LV handbags or Rolex with extremely gd quality that u'll almost believe it's true

*never go to those electronic stores in tourist area! they're sharks, charging unreasonable price, go to 'Boardway' if u wanna, i go there*
sight-seeing: well, to start with, the classics:
+ the Peak (bless u'll hv a clear day when u go up there, cause the air pollution thing can be bad)
+ night view at the TST pier of Victoria Harbour (it's better to look from TST side to Central) and u can actually try those ferry going between TST and Central
+ Stanley (some flea market and a beach too)
+ Repluse Bay (nice beach)
+ our pretty new airport
+ the Exibition and Convention Centre in Wan Chai (a bit boring in my opinion

, but quite popular for those China tourists)
+ Ocean Park (quite gd)
+ Disney (a bit small though, but how can u not go since u're here?)
+ Lautau Island with that huge buddha and the old fishing village called Tai O (recommend)
+ wanna go hiking, just go to Sai Kung countryside, and some would love to go to those 2 small island besides Lautau Island (they have great, fresh seafood)
EATING!!! (the most important!

)
1) dim sum, of coz, go to TST/CWB/MK 's chinese restaurant (they might be a bit expensive then other area, but better quality)
2) try those snacks or exotic food by the road in MK (dont worry, u wont get a stomachache and they taste
delicious, even they might look a bit ugly!!!

)
3) dessert, eat everywhere every type u come accross, especially those chinese one, we LOVE dessert.
4) there're many restaurant with diff. countries' food, like Thai, Korean, Japanese, Indonesia, Italian, American... pretty much everything u can think of... again, u can find them all in CWB/MK/TST
5) there're some nice 'upstair-cafe' in MK, just pay attention to some ad/signs on the street and u'll find some
6) try something they called 'chafing dish' (i found this term in a dictionary), u know, putting some raw food into a hot pot by yourself... that's gd
7) pub... mainly centered in SoHo area in Central
here's some brief suggestion, just PM me n i'll gv u more details (like where to get/see/buy any specific things or which exactly are those gd restaurants).
