Hey guys, I'm interested in getting a 21.5 inch 4k iMac. I want the 256 ssd option. No two ways about it. Don't want a fusion drive and definitely don't want a 5400 rpm HDD. As of now, none of the store models in the 21.5 4k have ssd. All have to be built to order. I am assuming that eventually they will have 'base' models availalble in the store with ssd. As of now the closest is a 27 in 5k with fusion drive, otherwise none of the other iMacs have either ssd or fusion as a walk in a buy option. Any guesses as to if and when Apple will have in store model s with ssd?
