This is my first Mac. I've been on Windows my whole life. Actually I bought a base model 14" M2 Pro in October but returned it after 3 weeks when I saw the M3 event. Luckily Apple accepted the return as I was over the 2 week return period. I bought the base model M3 Pro for the same amount of money as the M2 Pro model I had.
I got the base model 14" M3 Pro because I wanted Space Black and 18 GB of RAM. The extra USB-C port doesn't hurt either. My use case is light stuff like browsing the Internet, Microsoft Office, music/movie streaming, chatting, etc.
I had a desktop PC before this. It got very outdated and I replaced it with this MacBook.
