Thirded. I got mine 1.5 years ago and I love it as much as the first day I got it.
The T480 running Ubuntu really hit a sweet spot for me. I could get 32GB of memory (double the memory of other developer laptop options) and it has hot-swappable batteries for extended coding sessions off plug. I'm not a huge fan of dongles either, so the built-in ports (ethernet, HDMI, MicroSD card slot, etc.) were nice.
