> I have no idea how Lenovo's ThinkPad T series differs from ...

My personal rundown and how they get assigned:

E - Educational / Lower office personnel spec

L - Office personnel you hate spec, but don't offer the E because they might complain.

T - Give this to all the technicians because they can't take care of anything and it will survive typically.

P - Give this to the engineers who believe having an RTX gpu will actually help them so that they are happy, and to the CAD operators who actually need it.

X - Smaller/Ultrabooks before the term got started, now somewhat a blurry line because T series have gotten lighter/thinner. But the X1 Carbon sure is a great way to spend a ton of money for a light laptop when a T-series would suffice.

Personally I stick to older used X series (currently x250) because I just enjoy a small laptop and they are dirt cheap now.

This still doesn't tell me how they differ. What are the factual objective measurable differences between E/L/T/P?

I was assigned an E14 once. Compared to a T14:

The case is all thick ABS.

It weighs like 2.4 kg, and the weight is unbalanced.

The USB-C charge only works at 20V, nothing less.

While charging it overheats and spins up the fans.

It came with a TN screen with terrible viewing angles, that could not be used in a brightly lit room. I didn't use the laptop for two months while I waited for a replacement screen from aliexpress.

Keyboard is much thinner, the trackpoint drifts easily.

Camera quality is worse, somehow it cannot handle sun-lit scenes. Microphone and speakers are similar to the T14.

It stopped receiving firmware updates after two years.

It uses about 0.5 W while suspended, so its tiny 48 Wh battery typically doesn't last the weekend with the lid closed.

The motherboard has design issues, a missing protection diode in the headphone jack microphone input ended up frying the CPU due to a ground loop. Meanwhile the T14 has eaten the same ground loop and even a 48V passive PoE in an accident and dealt with it by rebooting. A T450 from 2015 is still running.

Interesting, I own an E14 and it charges with 12V PD profile, stock ugreen powerbank. Maybe they differ across models?

Spoiler: they are all identical hardware, but marketed differently.

I think I got it:

- E is for economy

- L is for loser

- T is for tank

- P is for power

- X is for executive

Fine, but how is anyone supposed to divine all that nuance from a single letter?

As much as I hate Apple, they really do have product names down to a science.
