I'm a long-time PC user who has decided to switch to a retina iMac with upgraded cpu, gnu, and RAM (after market). I don't consider myself a power user but do regularly use the adobe creative cloud suite (especially Premiere Pro and some After Effects). I only do HD, not any 4k. My current PC is one i personally built for video editing and still does a great job (Haswell I7 4770K, 32gb RAM, 3gb nVidia you,etc). So, I don't need to upgrade immediately, but I want to move completely to Apple products (have been using iPads and iPhones for several years) because of the great new features between Yosemite and iOS 8. My only concern about pulling the trigger on the purchase now are the problems I've been reading about with respect to Yosemite. I imagine these issues should be corrected by software updates in the near future. However, I guess there's a slight possibility that this initial version of the retina iMac might be slightly underpowered for the retina display and that waiting for the next model might be smarter. If you can't tell, I'm anxious to make this transition, but don't want to be stupid about it since I currently have a perfectly good working system. I know this will eventually come down to my personal choice, but would like opinions specially on whether or not it' smart to wait to see if software updates fix the current issues. Thanks for any opinion.
