I bought a cintiq21ux about a month ago. and i haven't been able to use it due to steve jobs's genious idea... let's not put a DVI o VGA output on the imac...fucker. so i had to buy an adapter which didn't even work beacuse apple uses DVI-D and the rest of the world uses DVI-I. now i have to use a VGA adapter.... VGA SUCKS! so now my tooth hurts.
