I'm sorry, but it is now useless.
Hell no. There are many uses for the TurboTuner:
1) I fully extend the antenna on the train and complain about the "poor reception" whilst fidgeting with TurboTuner.
2) 4 out of 5 tri-athletes prefer TE + TT combo (increased upper-body training).
3) 2 out of 3 New Jerseyans use TE as a monitor using Video-In on TT. Personally, I love playing SCD games, on my DUO, using the TurboExpress as a monitor.
