≈1990–2002: The dark years: PC only.
IBM PPC: 2003 Power Mac G5
Intel: 2008, 2011, and 2014 15" Macbook Pro's; 2019 27" i9 Retina iMac
Apple Silicon: 2021 16" M1 Pro Macbook Pro
All of them.
SE/30, IIci: 68030
Power100* (Mac clone): 601
iBook (Bondi Blue): G3
14" iBook: Core Duo
Studio: M1 Max
Neo: A18
*The Power Computing Power 100 was far superior what Apple offered and at a lower price. Licensing MacOS nearly killed Apple. If Jobs hadn't returned and killed the clones, that might have been the last Mac I ever own.
I started my Mac journey with a 433MHz G4 Power Mac, in which I put a 1.3GHz Sonnet upgrade, if I recall correctly. That was a beast. One day I'll see if it still boots.
Core 2 Duo Mac mini
i7 11" MacBook Air
M3 Pro.
I started with an Intel 2008 mini just to tinker with (it couldn't do much), then I moved on to a PC for a long time, before finally coming back to the Mac world with an M5 Air.
I chose all of them, though I'm not 100% sure I had any IBM made PPCs.
I had a PowerPC 601 in my PowerMac 7500 and a PowerPC G3 in my PowerBook G3 "Pismo", but I cannot remember if either of those were from IBM or Motorola.
Other than that I had a Motorola 68K in my Performa 630CD.
Motorola PPC made the PowerPC G4 in my 12" iBook G4.
Intel Core 2 Duos in my MacBook (white plastic, which I think was the second gen with the Core 2 Duo), Mac Mini Server, and MacBook Air 11".
Also an Intel Core i5 in the "Baby" 13" MacBook Pro (2 ports) in 2019, which was so terrible that it's the only Mac I ever sold.
And that brings us to my - still going strong - current M1 MacBook Air with Apple Silicon.
I've owned at least one of every major processor class, thought not every processor model within those classes: my first Mac (IIci) shipped with a 68030.
I used a 512 KB Macintosh at work. My home 68K computer was an Amiga 500. I bought my first Mac in 2012 after using PCs for 21 years. My Intel Macs were a 2011 MBP 15", a 2015 MBP 13", and a 2019 MBP 16". I now have an M3 Pro MBP 14".
Still have my first Mac: mid 2012 MBP (now w/16Gb ram and 1Tb storage and the Intel dual core i5), M1 MBP 16" basic, M4 MBA 15" basic, M2 Pro MM basic, and a 2010 MM project (now with 16 Gb ram, 128 Gb storage, and the IntelCore 2 Duo. Most of this will be changing...) Had a few different configurations of MBA over the last six years, all with some version of the M chip.
