The T480 is on par with this thing - you have two batteries, one is external and you can upgrade it to a beefcake pack if you desire, it has the 8000 series intel CPU which is fast enough. It has awesome expansion etc. I prefer the AMD T14's these days, but they lack a lot of the features I liked that this person calls out. One bigger internal battery, it's easy to replace if you (when you?) need to, and has USB4 on the later models.
