I 'retired' a T510 in 2017 that's slightly deficient by modern standards, Google Maps in particular is not much fun to use on it. I think their durability is overrated; a clip broke on the bundled battery and it wouldn't stay attached after that, and some of the plastic strips around the air vent broke off from being caught on something while in transit. I'm not a huge fan of the red nipple in the keyboard but it was very comfortable aside from that.

Nowadays a tower suits me better.
