I just ordered an 20-inche 2.66 imac. I just learned there might be an upgrade version coming out soon but i wouldn't worry to much about it if the current one gives me what i need. There are two things that i definitely want to be able to do: 1) Edit HD footage from my canon vixia hv30, 2) Run Final cut studio at a later time. Maybe when we finally get the so mentioned stimulus package. NONE of this two would be done for living so I guess I could afford not having the perfect performance as long as I can get it done with out getting frustrated. What would the cons of this?
