still too expensive imo, especially considering they lower the specs. IF they would drop then entire line by $100 it would look much better: 21.5" - $999, $1199, $1399.
On the canadian apple site, the 1TB fusion drive upgrade or 256 SSD upgrades are $275. The 500mb to 1TB upgrade is $50. I have the fusion drive on my 27" imac and its worth it, I would never go back to regular drives.
