This is my answer. If Imac haven't an update 27th then we almost see maybe an upgrade of RAM in existing models, or maybe a decrease of SSD option?... I'm waiting for Imac update for 3 months, but I can't wait any more for my job, 27th I'll buy a 27"Imac i7 2TB m390. This will be a good option for video editing? I have one eye seeing what's happening with Surface Desktop.... Apple, i like you, but guys your upgrading are very very slow.... Thanks!
