I think it has to do with the fact that the EHD can be removed. Once you pay the $40 fee you can plug in a EHD if you want or not. If there was a DVR fee you just know there would be people calling in who only have a 211 saying "I didnt have a hard drive hooked up for 14 days...I shouldnt be charged for a DVR fee"
Gotcha, makes sense. Helluva a deal to allow me to go mostly streaming, but keep a few vital channels like Food,HGTV, History, Disc, TLC, ESPN and ESPN2.
