We take a look at the ThinkPad T480/T580. Really good machines even in 2020.
Lenovo ThinkPad T480:
Great ultraportable, Lenovo has a dual battery setup, 14" FHD IPS option, supports the Core i7 processor. A version with the dedicated NVIDIA MX150 graphics is available. You might not have the narrow bezel & the improved speakers of the newer ThinkPad T490, though - there are the 2 RAM slots enabling up to 64GB RAM, excellent keypad when it comes to getting work done.
Lenovo ThinkPad T580:
Bigger version of the Lenovo ThinkPad T480, has a number pad and 15.6" screen. Weighs in about 0.4Kg more than the T480. This is a straightforward workhorse, for those whom desires more than the Lenovo ThinkPad E580.
