Well, I was wanting to get rid of my computer and my ISP and just use iPad/WiFi; because, I thought WiFi was a stand alone, independent, internet service. However, from what you all are telling me, WiFi is nothing more than a conduit to my existing ISP which is dependent on my computer to exist. If that is the case, iPad even with iOS 5 could never fully work 100% without my computer, because it would need my computer to have an ISP.
I guess I could get MiFi, but I was going to get iPad WiFi + 3G, so what would be the point. A 3G service to go with my 3G service. lol Plus, from what I have heard about MiFi you can rack up a HUGE bill if you are not watching your bandwidth meter carefully.
