exactly and also understand that the 802.11g standard for wireless networking supports a maximum bandwidth of 54 Megabits per second (Mbps) so unless you're wired, you can't really see the difference.
802.11g is quite old, however. The current version of 802.11, 802.11n, supports rates up to 450Mbps. My laptop with a 2x2 antenna configuration (and pricey access point) does pretty close to the theoretical 300Mbps.
Incidentally, once you have a fiber optic connection between two points, you can do a lot better than 1Gbps.
