We haven't quite figured out the wireless business model.
I am now in an entirely different Starbucks clone in Hollywood Road. (The whole mid-levels / Hollywood Road / SoHo area in Hong Kong really is yuppie expat heaven). This one has free internet terminals for customers. This is a nice touch, and compliments to them. It also has wireless internet access. However, this is for pay wireless internet access. So it seems they will offer me a terminal plus internet access for nothing above the cost of a cup of coffee, but if I provide my own computer the internet access itself will cost money. That's a new one.
And yes, I do actually spend the majority of my time outside coffee shops, even when travelling. Really.
