Model lines: X is premium business, T is mainstream business, E is economy, L is legacy/economy (extra ports). So by looking at "L380 yoga" you know it's a 13" convertible with lots of ports and an 8th gen Intel CPU.

Also the battery can be swapped so you can take 2 for travelling.
They are not heavy but they are bulky indeed.
