Seeing as everyone has made wonderful (and sometimes innovative) suggestions so far, I'd just like to add something more basic.

It would be great if ALL the manufacturers gave us more options keys wise.

By this I mean:

61, 76 AND 88 key options on (almost) ALL of their keyboards ACROSS THE RANGE...

AND

a choice of Non weighted/Semi weighted/Fully weighted action!

Alright - maybe impractical - but dang - a LITTLE more flexibility would be nice!

eg if the Tyros 2 had 76 keys - THEN - I could take it seriously.

(I realise this is just MY personal wish and many folks do just fine with only 61 keys - I know, I know!)
