>Don't forget that Wifi needs to be properly positioned to work quickly.

And if my properly positioned you mean "In a faraday cage with only the AP and your station", you'd be correct. The issue is real world WiFi doesn't ever work that way. There are very few places where you don't pick up at least one or two neighbors using at least some of the channel bandwidth you need. Even inside your own wireless domain you have the hidden node problem, forcing wireless domains to be broken into small cells using low power greatly increasing the costs of deployment. Add that a huge number of cheap APs and computer drivers flat out suck and the average non-professionally installed wireless user is not going to see 50% of the bandwidth they should.
