Why use wireless, he asks??

"Why use wireless when wired is more secure?"

You've obviously never had a teenage daughter sitting on the settee in the front room with her laptop, surfing the web, IM-ing her friends, doing her homework and watching telly all at the same time. She'll still try to do this even with a wired network, and after you've tripped over the trailing network connection across the room for the third time, you'll get wireless too.
