Remember that bluetooth, cordless phones, microwave ovens, wireless mice/keyboards, wireless cameras and a host of other 
devices all use the 2.4 Ghz. band. It's becoming useless even here in the "sticks".

The data rates stated for WiFi are a joke, they can't come close to what they claim even in an interference-free 

I'm surprised we haven't seen a "what is a gigabyte" type lawsuit here, though most WiFi devices do have a disclaimer on 
the package, it's printed in "Enron Beelzebub" font at a less than one point size.
