Haha yeah, I'm with you on the extra things on my desk! Plus, more wires!
I like the design of the M1 and was seriously considering it but when I saw it in person it hit me how much smaller it is, the 27" plus the bezels, so you're losing screen space and then just the entire 'thing' is smaller. I'm looking at replacing this iMac late this year I reckon, so fingers crossed something appears.
