Great timing.
Last week I bought my first Thinkpad, a T460 16Gb 500GB SSD version, and I just love it.
It came with Windows 10, but I put Debian 13 GNOME on it and it flies.
The T460 is a very basic model, no keyboard backlight for example, but with an awesome feeling keyboard, responsive trackpad and, of course, the little red joystick in the middle of the keyboard.
My background, though, has been Apple Mac's since 2007.
2007 20" and 2009 27" iMac's. A 2010 Mac Pro 5,1. A 2010 13" Core Duo MacBook Pro, a 2015 15" i7 MacBook Pro, a 2021 13" M1 MacBook Air and 2022 13" M2 MacBook Pro, and every possible Apple gadget available at one point or another.
I've used Open Core Legacy Patcher on several of them when upgrades were unsupported by Apple.
However Linux on a Thinkpad is a real game changer. It is brilliant.
I now have my, 14" Debian Thinkpad T460, a 2010 13" MBP running dedicated Kali Linux and my 2015 15" MBP running, of all things, GhostBSD.
I'm very happy to be free of Apple's corporate crap and ecosystem tbh.
My advice...
Go for it.
