I have been Mac user since 2003, but since 2011 I discovered how good and versatile are the IBM (now Lenovo) machines.
There’s a reason why ThinkPads are widely used in the ISS: this machines are so reliable, easy to maintain and fix, compatible with most Linux distros and most important: hackable!
Here the current list, but more to come, of course!
X250: wife’s work laptop
X230: i7 CPU version, SIM network, my laptop. W10 / Linux on USB
X240: wife’s everyday laptop. W10
X60s: consolle laptop (Traktor). W7
X60t: used as graphic tablet (Photoshop, projects, notes…). W7 Tablet
M58p: 6163 version, used to program Arduino and other electronic projects. Linux
E530: wife’s old everyday laptop, broken, will reborn as retroconsole emu. Linux
ThinkVision T2220: my main station secondary screen
My main machine is a Mac, but I am planning to change soon.
