If anyone is looking at going with a ThinkPad, there’s a neat website that watches the Lenovo Outlet and reports the offerings in a simple tabular form: https://lw.ofwiz.com/
I’ve used and continue to use ThinkPads for work. In my experience, they’re engineered and designed well, perform solidly, and they travel well. Batteries for them seem to be on the market forever. I just bought a new pack for a T500 that I still use – that thing is more than a decade old now!
My current daily driver is a W540 from about 5 years ago. It started out with 16GB of RAM, but I found that 32GB made it so much better. It’s been a solid performer for years until the Spectre related patches started to come out and the drop in performance was bad enough that I’ve been looking for an upgrade for a while.
So, I just very recently got an outlet P52 w/ 64 GB and a Quadro P2000. I need to get my aftermarket Samsung 1TB NVMe SSD installed to replace the stock HDD and then go through the whole software install process – so too early to give a review. There was a 128 GB configuration that was not much more, but I hesitated and someone already bought it.
There’s really no need for docking anymore – wireless mouse and keyboard plus a miniDP cable takes care of my needs most of the time. If I need USB peripherals connected, I do have the one USB 3 hub.
Whatever you get, make sure you have a system that you can easily upgrade to at least 16GB and preferably 32GB or higher.
