Most of the ISPs in HK .. same shit different packages.
Assuming you're not running server type apps on your connection (i.e. web / file / db servers with access to the world), you're going to find other limiting factors on a home network.
WiFi cards, 100Mbps ethernet cards on slow PCI buses, your Linksys router etc etc ... not a lot of the gear used in home desktops is going to let you take advantage of speeds higher than 100Mbps.
AND, we're not even touching the fact that at the end of the day, most connections are down to the ISPs overseas links.
