JJ O.S.2 vs. the 4k's functionality

I understand that the JJ OS2 is pretty close to how the 4k functions.

Are there some hints being made here?

And would anybody like to elaborate on this?

The only hint I can give you is to sell both those 4k's and cop a 2500, s950, and a Fantom or Reason 4

What else would you like to know?

4k has a stronger processor (or multiple strong processors? one of the two, i don't know)
os2 gets close, and does some things that the 4000 does not, but the 4000 does more things that os2 cannot.

that being said i think more workflow customizations, shortcuts and additions have been made for os2, just because there's someone out there listening to user requests, big and small

os2 isn't multitimbral....which is a goddamn shame
