What is WiFi?

Alright, I'm not actually that stupid. :)

I'm talking about wifi for arduino... like this (http://www.sparkfun.com/products/9954). The page mentions that it "equips your Arduino the ability to connect to 802.11b/g wireless networks." But is this internet? Could I use this in place of an eth shield? (I am thinking not) Which leaves that it just connects to the network... but what can it do? How do I interface it with a computer? Or is it just wireless internet?

Thanks!

Have a look at the example. http://www.sparkfun.com/tutorials/158

At that price it better butter my toast in the morning while I surf on my Arduino. ;)

So, I can use it directly as an internet module? In the example from 02660, sparkfun just sent commands over to the wifly shield... they didn't use any http.

By "internet module" I meant http. I was simply wondering whether I could get http data using a wifi shield similar to an ethernet shield. But that has been cleared up. Thank you all very much.
