If I'm home, I watch it on my television.
If I'm mobile and out of range of the network anyway, you just copy it to the iPhone with tivo2go.
Again, it's cool and I can see the appeal with the streaming but it seems like tech in search of a niche.
Maybe for people without a TV or something.
I have 2 TiVos in my house, and modded both of them (an original Series 1 and a Series 2 Humax TiVo w/DVD recorder). I'm more than familiar with TiVo.
The main difference here is that I'm recording straight to my Mac with EyeTV. Frankly, with a 24" iMac, it is fantastic to watch TV or any other video. The key difference with the EyeTV approach is that I can edit the shows that I record; I will sometimes burn them to DVD with Roxio Toast - which integrates the EyeTV software to make life easy. The software already had the ability to record the video and put it on an iPod (iPhone). Now Elgato added the ability to stream my edited TV and/or movies to my iPhone with the software. That's a nice, free, bonus!
EyeTV is definitely a niche product. It works very well for me, and the new iPhone streaming video support is icing on the cake. I haven't replaced my TiVos, but this is great stuff, too. Don't discount what they're bringing to the table...and it's really not too expensive either!
