I picked up a 2025 P14s Gen 6. Wanted Ethernet and the ability to easily swap both RAM sticks in the future. Apart from the soldered WiFi chip, this computer is by far one of the most modern and repairable ones I’ve seen. Perfectly runs Fedora KDE, too.
T series are also fantastic, but at the time it wasn’t as repairable given one RAM stick was soldered and the other was replaceable. Also because of the form factor it didn’t have Ethernet.
Can’t go wrong with a P series if your needs are similar to mine in a computer for long-term use.
Edit: Forgot to add that while my P14s Gen 6 is great, the biggest complaint is the soldered USB C ports for power delivery. That's a huge point of failure. I mitigate the weak point by using a magnetic USB C cable. It's nice to see the the new T series has modular USB C / thunderbolt ports and remediates the weak point that was a common complaint for users.
