I've been reading about Tivo's new Whole Home DVR product coming out soon. I am trying to decide between buying a 3rd Tivo in my house (would be 2 Premiere's and 1 S3) or waiting for the Whole Home DVR. What is the difference betweeen these 2 options. Is the Whole Home DVR basically a Tivo Premiere box? If you can transfer/stream shows, how would the regular Tivo Premiere differ? Please help me clarify. Thanks.
