That means I can no longer afford the highest iMac... the others better not have crappy GPUs.
Hopefully it means you wont need to buy the top one if the upgrades justify the cost increase (depending on your needs). I'm thinking of the top 21.5 for me, for that price I would like a dual HDD SSD a better GPU (retina would be nice but not needed) and all the other hardware tinsel that should be guaranteed this year.
