Tivo enters Gilette v Wilkinson Sword Razorblade Race (But With Tuners)

Tivo are entering the equivalent of the Gilette v Wilkinson razorblade race with their latest DVR product - Or is it to appeal to the Frequent Flyers amongst us who are never home to watch TV - (Permiere Elite is a definite FF Award Status).  A retail DVR with four tuners allowing for simultaneous recording of four different shows while viewing a fifth recorded program. Plus a two-terabyte hard drive that allows for up to 300 hours of recorded HD programming:  Two times more recording space than current offerings. So who will be next to bring out 6 tuners so you can watch 1 program whilst filling up your hard disk with an unimaginable amount of stuff that you will never be able to watch?
