Besides my personal preferences, it DOES seem like there's a big hole in Apple's product lineup. You can get a 24" iMac for $1500, but the next model up is a base Studio with Studio Display for $3600. I would think that a 27" iMac with similar specs to the MBPs would be a similar price (I'm assuming a 27" LCD would be similar to a 14" or 16" mini-LED, price wise)
