The PC show is really sucky. Not much to see at all. The walkways are narrow, the vendor mix is not focused.
I did a quick comparision of HDD prices with those at Sim Lim this week, and I found it to be about the same. I did see some rather good deals on DVD writers and CF cards but nothing to really shout about.
Ironically, I picked up a rather good card reader at the Book fair for 9 bucks instead.
So IMO, unless you've already decided what you want to buy, no point going to this show. The previous one earlier this year was much much better.
