Donny,
I've spent many hours on the T2 at GC - about a year or so (silence the critics please)
1. Keybed is awesome
2. Pop-up, much larger display
3. More styles and sounds
4. Mic volume control on deck
5. Optional hard drive
6. splits
Besides, (2) S900s is boring. I want something a bit different for live play.
I love the 900, as you know. I want it in my studio now.
