I have an ancient 24" mid-2007 iMac. Wondering what I would need if i wanted to replace it with a notebook instead of another iMac and would it be worth it? Especially interested in hearing from others who have done the same. The portability would be nice but not required. We have work pc laptops, but it would be nice not to have to be tethered to the home office when we want to use the Mac and vice versa if I want to watch a movie /steam something / Youtube etc, I could always "dock-in" to use a large external monitor. I'm thinking we need a monitor (but Apple doesn't make their own anymore), some kind of docking station or hub, etc etc. The most taxing thing the iMac is used for is housing our photos in Lightroom (no processing or image manipulation being done). Alternatively, we just buy another iMac, either a current spec 27" or keep waiting for Apple to release an update.
