not a clue. Those thigs are way too rich for my blood.
I've met the people behind duet on several occasions. Very helpful, good people.
So best to just ask them :-)

holy crap its £222 !
That's bloody ridiculous.
I don't care how good it is, that's sheer daylight robbery !
No wonder they're helpful :-)

I think I once spent just over £100 on a motherboard for a clients gaming pc (£500 on graphics cards) - but never before or since.

What justifies that kind of money ?

More importantly, has brian printed anything yet ???????
