Nice!
There are also a few sample based pipe organ that are good.

Wonder if Ipad will be and alternative to computers. Seems a faster setup and less problems than computers but yet a computer seems to be quite a lot more versatile and offer higher quiality.

If you at the moment were to add a dedicated laptop or Ipad for a varaity of sounds incluing pipe organ and piano I guess the choice still had to be the laptop or?
