pgadey and philips told us about their computers, so I'll tag along.
My main computer is a ThinkPad L412 with an i5 CPU and a 128GB ssd. I have both Ubuntu GNOME and Windows 10 installed.
I have another ThinkPad (E530c) running Ubuntu that I use at home.
The third laptop is an old ThinkPad R51 (this one still has the old IBM logo on it) running Windows XP that I bought for fifty bucks to play old games like Tiberian Sun and GTA 2.
