If you have 6Mbps DSL and a single PC on 802.11G can't keep up, you have a problem with your wireless setup. A properly configured 802.11G setup should be able to peg a 20Mbps connection, and that's figuring in real-world conditions.

So basically, most people wouldn't get much benefit from a wifi device above 27mbps at the absolute most. However, a desktop computer could be plugged in directly (or through a gigabit router). Even in that case, though, I'd bet that the computer itself would have trouble keeping up.

When you start to figure in all of the variables (operating systems, GigE, etc.) your average Windows PC isn't going to be about to take advantage of speeds above 100Mb with any regularity.
Depending on environmental factors and number of devices, 802.11n whether you're talking about 2-channel 2.4Ghz or 5Ghz, can provide speeds that are easily comparable to wired connections. I have a Netgear 5Ghz bridge I use for testing and I can write files to my NAS at 95Mbps over a wireless connection. That of course assumes that the NAS can write at those speeds in the first place, that I have excellent signal strength and line-of-sight between the bridge and the AP, etc.

Your builder isn't entirely wrong. By and large, while wireless isn't as good as wired, it's still "good enough".
I usually recommend that if you're building, put in wires. If you already have a house, wireless is generally a better option than fishing the walls...
