So, I just tested both and can say hands-down the Slingbox (350) is light-years ahead of the Stream. In fact, the Stream is not even usuable outside the home. Here's my setup and results: Home internet: 30 Mbps down / 5 Mbps up Test site speeds: 5 Mbps down, 7 Mbps down, and 30 Mbps down Tivo Premier + Stream Tivo Premier + Slingbox 350 With the Stream, I could not even watch when viewing outside the home due to poor viewing quality, regardless of the testing site. All I could ever get was 2 bars on their video quality which was quite unwatchable. Viewing live TV was cumbersome due to the need to "record" everything. Moreover, half of all the shows I wanted to watch were not available due to transfer restrictions. With the Slingbox, I can receive HD quality at all of the testing sites. It really is great quality. Interface is great owing to the fact they natively integrate the Tivo remote in a couple of different ways ... including seeing on your screen the full Tivo remote so you can navigate virtually anywhere. Did not need the IR blaster since it controls it over the network (which is great). I should add the Slingbox ipad app had some pauses and issues, so I need to try it a few more times and see if that is true always. All in all, I returned my Stream ($90 from Fry's) and kept the Slingbox 350 ($148 from Fry's). IMHO, Tivo has a LONG way to go to reach the quality and ease of use of the Slingbox, not withstanding the copywrite protection issues of many shows.
