I didn't want to run cables so I've decided that a wireless adapter would be the way to go. Bought the TP-Link from Challenger at S$29. The setup was quick and painless as you can see from the video. I think the only negative is the removable cap. Come on... is it too much to do a retractable type?
Anyway, my lowly 6Mbps internet works great on the adapter and that all that matters to me.
PS: you won't need this device for notebooks and new gen motherboards with inbuilt wifi.
