Recreated this screenshot from 21 years ago (first Mac) on my new Mac.

• 2003
• 2024

How does 2003 and 2024 compare?
Nowadays I'm using the regular Apple Mail.
X11 forwarding still works but is not really used.
Some Linux host is still around. Mac remains the main device though.
Interestingly Linux still is a Intel device, whereas the Mac one is (again) running on a non-Intel CPU.
