Hi,when do you guys think the next refresh will be for the 27"? This update dident give me the urge to go and grab one.felt a bit underwhelming for my own taste. Maybe its because id like nvidia gpu and ddr 4.but i just cant get myself to press that buy button for this one. Lots of money,And i wanna feel 100 % satisfied with my imac purchase. Although if the next refresh is gonna happend in one year from now i may buy myself an imac soon.but ofc its hard to tell the future.is there a pattern in refresh cycles for imacs? I have never had a apple computer in my life but the im really drawn to the imac,it just breaths quality. Thanks.
