I have an old x61s, so it's not even as old as this. It does work perfectly. However the screen is bad--very dim, even on maximum brightness. It seemed fine back then but compared to the x230 I would never go back. Otherwise, though, there's nothing about the machine that makes it antiquated for most uses (web, video, etc.) Even the 1024 x 768 would be tolerable were it not for the dimness.
I can testify for the sturdiness of these. And X60's aren't the most robust of the pack. But I bang them once a week and yet no glitch. The platform is ancient, a Haswell ULV will be twice as fast for less than 25% of the TDP, with many added niceties (64bits, vt-*, a decent gpu, ...)
I own a T400 and it saved my back twice when sliding on ice. After 5 years of taking it everywhere, it looks like it was barely used.
I love it, but damn... a P8600 Core 2 Duo in 2013 is noticeably slow even in browsing.
