Im a new user here and am about to take the plunge into buying a Mac. Never owned one before so this is a big deal for me. Im debating between a Mini vs an iMac. Heres my situation: - Heavy Adobe Lightroom work. Want fast performance for import, preview generation, module change, and going from photo to photo. - Very occasional Photoshop work. Its a non-factor. - Dont do much video work but will begin to. Even then it should be limited to basic splicing, simple edits, and exporting to lower resolution for sharing. - Dont play games, wont be watching movies on this machine. - Have a 27-inch monitor running 1920x1080 and my photography work has outgrown it so its time to upgrade as well - All data in a Lacie 2TB USB 3 external drive, backed up to another drive of same. I consider a Mini (upgrade to i7, 16MB, 1TB fusion = $~1399) primarily because a computer will only last 3-5 years before you dont want to use it anymore, whereas a good display will last 10 years or more and not get obsolete. So decoupling the desktop from the display seems to make sense. I can get a Dell 4k (very good monitor) for $700, and when its time for the Mini to go, I will still have the display. iMac Retina 5k is of course beautiful but when its time for the desktop to go, you throw away the display as well. So will this option entail upgrading to i7 (+$250) to maximize longevity? Money is a factor of course, but making the right decision is more important. Thoughts?
