I bought a WiFi model on Day One then sold it when the 3G came out. Originally I did not want the 3G, but as I used the WiFi realized it might be nice when WiFi wasn't available since it was at the time no commitment for 30day unlimited service. Of course we know what happened weeks later and "unlimited" effectively became "subscription required." Today Virgin Mobile USA (owned by Sprint) will start selling it's PayGo MiFi for $150, about the cost of the iPad upgrade from WiFi to 3G. Service is more expensive at $20/300MB, $60/5G, etc., BUT you can use it w/ other devices, even simultaneously for the multi-taskers in us. Also coming out is BestBuy's own branded, but Sprint serviced, PayGo service at the similar prices As a 3G owner, knowing unlimited PayGo is dead, this makes me very jealous. Well done WiFi owners, well done. I think next year I'm going WiFi all the way.
