someone wrotei can crack a wap and wep in 3min but for real world example you need to crack wpa2, who's stupid enough these days to use wap or wep?
There's plenty of people who still use WEP and they ain't stupid they just don't have much knowledge in wireless and networking stuff and their router was set up by their ISP or someone else.
So not everyone is as smart as you are :)
And learning new things is always cool, by learning this process of cracking WEP i learned lots of stuff about Linux Ubuntu and BackTrack 5
