I'm one of those who keep browsing Thinkpads until I gather the following conclusions:
- Need 4G LTE/5G WWAN?
Thinkpad X, X1, T series. (eSIM is supposed to be supported, but I don't know how because I never owned one).
- Need a performant dGPU (Nvidia only)?
Thinkpad P series.
- Need digital pen with pressure sensitivity?
2-in-1 or Yoga in the name
- 5-yr durability (judged by relative cost of 5-yr warranty)
Any Thinkpad that is not Z series or L series. But beware that if you add lots of options esp OLED screen to the higher end laptops, the 5-yr warranty costs will still blow up.
- High resolution (i.e. high PPI) screen (eg. 2880x1800) > 2560x1600
Thinkpad X, X1, T, P series
- Soldered RAM (dual-channel)
Thinkpad X, X1, T series
It turns out that even soldered RAM is as slow as removable sodimms due to huge CAS numbers (lax timings). Don't get mislead by the high frequency rating of soldered RAMs.
- Numpad
16" screen and larger.
IMO, the only reason to buy Windows laptop is to get
1. digital pen WITH pressure sensitivity AND touch screen AND high PPI screen (i.e. 2-in-1 or Yoga)
2. Nvidia dGPU (for RTX AI, Video editing, 3D modeling)
3. 4G LTE/5G WWAN
Hence, if you buy any Windows laptop without any of the features above, perhaps check if your workflow can be done on a M3 Macbook Air laptop. The responsiveness, and HDR support for Windows laptop is basically trash compared to Macbook (Pro for HDR). You can try to get better battery life with AMD CPU (or Qualcomm Snapdragon X) on Windows laptops.
Personally I own the Lenovo Yoga Book 9i for reason 1 and dual-screen. Nothing like this exists in Mac or other brands.
