As TC points out, one of the biggest unknowns is how they are going to handle the bandwidth demands - and suitable reimbursement for the carriers - how that will be priced/packaged to keep from pinching the end consumers too painfully.

Yes, I have to wonder if the long (till Q1 2010) wait isn't as much due to hashing out possible deals with potential wireless carriers:

"And we shouldn’t have to wait a year or more for the device, the goal is Q1, according to the report. This indicated just a small slip from the Fall 2009 launch that we had initially been hearing."

[ Though on reflection, the whole customize-your-own-cpu is probably throwing in some of its own monkey wrenches. ]
