I'll give this one a go, but be warned... T users are almost as creepy as Saturn owners. I used to be a Nuendo user. It's a great piece of software but I had a few problems:
1) It's (extremely) expensive. Even though I had a copy, none of the people I play/write with could justify the expense, which means the only real option for sharing projects was to bounce tracks and share the raw wave files.
2) All the "professional" features kept me noodling through endless menus and reading and re-reading documentation. This is all time not spent writing music.
3) The user interface is in the (decidedly-not-so-clever) emulation of hardware interface camp. This pretty much blows on a computer for anything but the most trivial apps and usually requires dual monitor support and the addition of (expensive) daw controllers so you can pretend you are mixing on a console.
So, I started a project that required passing back and forth full mixes between a pc and mac. I had heard about T which at the time had some pretty great features like freezing and single file project export with or without compression. Plus, it was only $80. I started using it and a few interesting things happened:
1) I stopped experiencing import/export problems!
2) I lost my 2nd monitor since everything was so well contained in a single screen; no more window switching!
3) I spent time making music instead of fiddling with some obscure video timecode feature.
Bottom line, T doesn't get in the way of me writing music. If you are a musician as well as an engineer I think you will find it a great fit.

P.S. It has the most flexible routing I have seen in any software.
P.P.S. The kvr forum is more interesting than the mackie forum
