Costco has the Intel Mac Mini on sale for $549 right now. I have a 2011 iMac 21.5" running High Sierra. First, is it possible to use the iMac as just a display? It has one thunderbolt port, which currently has an SSD drive I boot from, but I should be able to plug that into the Mini. Second, any drawbacks to the Intel rather than the M1 - which means I'd need a new display? I use it for media watching, web browsing, and email. No gaming. No video editing. But as you can see I do hold on to my tech for a long time before replacing. Would the Intel Mac likely last me a long time or will the M1 mean it will stop being supported? The sale is time limited so any advice would be appreciated by this Senior on a fixed income.
