Here is my situation. I have a 2012 non retina MB pro with a 500GB hard drive that is now nearly full, with photos etc. The computer is basically unusably slow and therefore I don't use it. But originals of all my photos are there (and backed up on an external time machine drive). I also have a 10.5 inch ipad pro and 2017 NTB MacBook pro with a 256GB SS drive, which I use for my everyday life. I also should say I use iCloud to store my original photos. I don't really need to buy a new computer. Do you think I am ok just depending on iCloud to store my photos? If not, let me hear your ideas...
