I have a Touch on order, but currently use both a Duet and a Transporter (Modwright modded).
The big advantage of the Duet is you can have the receiver portion in a closet somewhere, hooked to your preamp/amp and the only visible interface is the small hand control. Early versions of the Duet software were a bit buggy, but the latest releases have been stable.
The touch has a much better screen, a much better DAC (which if you're running only digital won't matter to you), but offers less flexibility from a remote-control standpoint. You can use the iPeng app for the iPhone/Touch which works well as a remote control. But with the Duet, you won't need a separate remote.
From a sound quality standpoint, I think the Touch is better in every way. Users report near-Transporter level performance. I've been using the Duet Receiver into a Perpetual Technologies P3a DAC (also Modwright modded), and it seems like a fairly decent transport, but the combination does not in any way challenge the quality of the Transporter sound.
There's been some discussion about whether the Touch is likely to become an orphan product, since it seems that it is not getting much development/support from Logitech. The Transporter is no longer in production either. One wonders whether Logitech bought Slim Devices only to run it into the ground. Anyway, long-term support might be an issue.
Hope this helps!
