More info regarding high speed internet and wifi at WDW, http://www.intercot.com/infocentral/...wtoconnect.asp
The CR has computers in the room, which still remain free to use and internet is included at the Swan/Dolphin. I'd be curious if Disney does add wifi at some point. They may start with the resorts that are "convention" specific or classify some rooms as business and include the service exclusively to those rooms. I imagine that Disney doesn't want their guests spending time in their room and that's why it can only be found in public areas right now. They want you out and about, spending your time and money in the parks or doing other recreational activities. While not having it available may affect some peoples choice to stay on site, based on the sell out numbers that we're seeing lately, I don't think it's having much effect on their bookings.
You can always look into bringing your own internet with you. I know that I have ATT Wireless and they now provide that service and plans now.
