should I get one ? So how is this iMac working out ? I've been wanting to get one for a while and now I need a new computer so it's the time. But I am a bit concerned: . First iteration of dual core . previous iMac (only including the most recent design) have had widely known problems (including those admitted by Apple), at least originally, I know from direct experience (yes, Apple repaired w/o asking questions) . noise ? . and any other problem from a user perspective who want. thx guys !
