I recently transitioned from desktop to a T14. Although my time-with-product has been relatively short (a week or so), I am really happy with it.
Pros:
- Ryzen 7 4750U is awesome.
- Lots of RAM.
- Easily customizable orders from Lenovo with great features to add
- Renoir graphics are pretty solid
- keyboard is fantastic, classic ThinkPad feel and usability
- Easy to upgrade. Ordered with a 128GB nvme and immediately upgraded to a 1TB, saved about $200.
- docking station allows for easy desktop use with multiple monitors
Cons:
- libfprint is still in it's early stages imo, so the finger printer reader is tough to set up with linux.
- no backlit keyboard (on the one I ordered, can't remember if that was an option or not)
