True! T series or P series are much better made. I’d also advise heading over to Lenovo support site and checking the service manual for any machine you’re interested in, just to make sure that the features you may want to upgrade are upgradable.
I’ve noticed Lenovo doing a lot of SOC style systems ala Apple where your RAM is one and done. It’s mostly been on the thin/light segment but…
My biggest complaint has been the fact that they don’t put the USB C inputs on a daughter card. I don’t know what the cost savings is, but I literally had two machines that users had killed the USB on that spent close to 10 months waiting on parts for a warranty repair.
It’s supposed to be tuned more toward heavy workflows, such as rendering and CAD. It has support for more RAM (6TB) and quad SMP along with ReFS, and SMB Direct.
I only found out about it because we needed a beastly set up for combining lidar and drone aerials in Autodesk.
