I currently have a Premiere upgraded to a 2TB drive with lifetime service. While the unit works fine it is sluggish as the Premiere's are prone to do. I would like to stream Tivo content to my iPad, too. I know I can do this with the Stream, something I had but got rid of because of how loud it was. So I guess my first question is the Roamio noticeably faster over the Premiere in the menus? Are all menus HD now or, like the Premiere, is it sort of piecemeal? I know the Roamio Plus only has a 1TB drive: is there any way I can move my 2TB drive from the Premiere into the Roamio and have it update to the latest Roamio software? I'd rather not lose an additional TB of data if I don't have to. Or am I being stupid and just stay with the Premiere since it has a lifetime service?
