O-yes , USB 2.0 is important but...

It should also have FireWire !

Tyros 3 ( 76 key ) / FW 400 or 800

Tyros 2.5 ( 61 key ) FW 400 & USB 2.0

Also after much thought , the T - 2.5 should also have built-in speakers.
Similar to the S900 only better , say 30 watts per side , or even 25 WPC.
Ported acoustic designed enclosure , with in the body of the A/KB.

USB ports ( 2 ) one in the FRONT !! , that`s important !!

Real plastic buttons and real switches ( like a Motif or Tyros is now ).

Well , that`s it for now , back to the drawing board !!
