My first laptop was manufactured by Hewlett-Packard, second by Sony, third and fourth by IBM. The Thinkpad X41 made me stop looking for another maker in this device category. I already had a IBM “Aptiva” desktop computer with Microsoft Windows 95 at the time, but i didn’t know “Thinkpads” existed back then. My last Thinkpad is the X60s from 2006. Both are still working today, but only the X60s has Windows 10, while the X41 is still running Windows XP. They are not much heavier than modern notebooks, but many hardware parts can be swapped, like the battery, keyboard, memory, and harddrive, as i have done. I took them to school, press events, university, and basically everywhere, till they got too slow for my needs. Since they were always on the expensive side, i stopped buying them, although i like their contemporary devices. Without IBM personal computers i probably wouldn’t be here. Thank you and happy anniversary, Thinkpad.
