Zuki,

The T2 was very nice, but it was a pain to move around...you'll need a good case....AND you still have 61 keys like the S900.

I took a T2 around with me for several months for many store demos and it was not as easy to deal with as the S900, although it wouldn't seem that way as it is not that much heavier or bigger...just more awkward.

I just put the S900 in a gig bag since I'm the only one moving it.

I'll stick with my S900...I'm quite happy with it's performance.
